I'm actually not quite sold on that last point you made, and here's why.
Yes, in some cases I absolutely do think that getting help solving a problem from others is good.
But I do also think that using your own resources is extremely important.
In my profession, we talk about a client-centered, strengths-based approach. This means that, for example, if you were a client of mine, I wouldn't just be saying, "Okay, here's this money, here are these resources, here's this doctor to give you pills, have a nice day". I'd be talking to you about using your own skills, your strengths, your abilities, to better your position. If you needed help finding those strengths, that's okay. If you needed a bit of a nudge from the outside? That's okay too. And there really are situations where no amount of internal strength is just going to auto-solve a problem. It's a variation on the old bootstrap scenario.
So it's not that I think it's my complete responsibility to educate anyone and everyone. I just feel that, hey, if I -can help, why wouldn't I at least try, if I'm able? And most times I'm able.

You're correct in that not having a guide close by may teach most people eventually to just ask you questions. But the goal isn't just to teach people to talk to you, because, hello, of -course they're going to talk to you if you're the only one present. The goal, at least in my view, is to teach people -NOT to talk over you or past you. They are two different scenarios, and in my own life, your solution just doesn't suit because the people whose behaviour you're hoping will improve aren't actually getting a chance to deal with the problematic situation.

I'll put this another way.
I have categorically never dealt with someone who refused to talk to me when I was alone and they needed to interact with me. Not once. Why? Because people seem to realize that when it's one-on-one, all the normal rules apply, for the most part. There's nothing to solve there.
But the instant there's another person involved? Suddenly, bad behaviour can start. And while it's not my actual responsibility to fix that, my empathetic side says that if I'm capable of giving enough fucks to tolerate the inconvenience while perhaps getting someone to rethink what they're doing, it might just help someone else down the road who perhaps has far thinner skin or who, unlike me, might now how to advocate for themselves properly.
Again, I'm not faulting you for not doing this. I'm not even trying to go anywhere near that. As I said in an earlier post, you do you. That's fine with me. But this outlook works for me. Because at the end of the day, I am hoping to affect some small, positive change on the world. I don't just want to pass through it making the fewest waves possible. If I have to gently set someone straight, that's okay with me, if the alternative is that biases aren't challenged and bad behaviours continue. Doing it your way, in my opinion, is less likely to work because it's not invoking the problematic situation in the first place. If all I cared about was getting good service and treatment for myself, then sure, it works. But I care about more than that.
So this is my reframe. You structured it as me expecting others to solve problems for you, vs. you expecting people to deal with their own shit. For me, I see it as me caring about a broader perspective and the potential experiences of others, while you are more interested in the direct impact on you and whatever you're doing. Rather than socialist vs. antisocialist, it's more individualism vs. collectivism. Again, no negative judgments, but I think this distinction, while you may feel it is a hair-splitter of an argument, is quite important.

aIt must be harder for those of us who have an SSP, which would be equivalent to your guide. In most cases, SSPs do not provide direct sign language interpretation, although they can if they are fluent in TASL or protactile. I still have enough hearing to be able to answer for myself and so far haven't had a need to use an SSP yet.

I just answer the questions I know are directed at me. Most of the time when this has happened, I'm with someone IU'm close to (parent or wife for example), so they know to just shut up and let me answer. My Mum used to say "Why don't you ask him?"

I know it's tempting, but there's no need to be rude unless the target is being particularly dense.

It's worth bearing in mind that nobody likes to be demeaned. If you say "Oye, look here fuck face, I'm a human being too", the person on the receiving end of that is going to feel just as belittled as you feel not being asked your address directly. Difference is, you're on a forum full of blind people you can ask for advice,. That person won't have a forum of other people who get their shame, so the easiest option is just to avoid disabled people in the future.

Psychologically, if you use a persons' name, or go out of your way to put them at ease, they will remember you, and be more likely to want to interact with you in the future, because you make them feel special. If you go out of your way (no matter your intentions) to make them feel stupid, or inferior in some way, they're going to want to avoid you, and possibly others who remind them of you in the future. It's like small-scale PTSD I guess.

Personally I'd go with just calmly telling the person that I can answer the question they're asking, or not even that... Just answering the question.
When I'm at a restaurant, lots of times I won't know the person is asking me what I want, so Mom will just say, "Matthew, He or She is asking you," and I'll go... Oh, sorry. I'd like blibbity bla, with a side of whatever it is.
When I can actually hear the person, they'll ask me... And honestly I still don't realize it most of the time because there's lots of people sitting around the table, or whatever the reason may be.
I'll wait about 2 or 3 seconds and then say, I'd like whatever my order was.
Sometimes they'll ask Mom what I want, and usually I tell her beforehand, so in situations where it's really hard to hear or the person taking the order is far away from me, she'll just answer.

For me, knowing that someone is talking to me is just an instinctual response. Knowing that I need to answer a question is just something that I've always done. My Mom when we go to medical appointments and such is really good at ensuring that I'm the one answering the questions; she never answers in my stead unless its a question I'm not sure of. I've also gone to areas on my own and definitely get treated normal in those instances.

hi
when this happen, I want to break every wall and door infront of me, and shout at him to ask myself else than others
I really hate this feeling. I just can't see, just this! I surprized when found out that this happened in US

@38,
How on earth haven't you heard of Blibbity bla? It's currently the most popular food in the lower 48 states!

LOL, I was using it as a sort of placeholder.

@36, no, I don't. Its just an instinctive nagging feeling, I think. I can't really describe it.

I guess I am blessed, since I don't exude any blind mannerisms and still have a little bit of vision left to use it to sorta focus on different interesting things making me seem more similar than not. That's not to say I haven't encountered this problem. Like post 18 I believe, most of the time it doesn't bother me, I go with whatever's most convenient honestly. I haven't really had this issue lately so can't say how I'd respond today, but then again I surround myself with people who are very good at this, as in they don't speak, and I speak for myself.
Which brings me to my second point: people who I'm supposed to interact with long term, or might in the future. If they behave like this, I will simply know to stay away from them. For example I was once "chatting" with this guy who owned a radio station to see if I could come do an inturnship there. He kept asking the person with me, so guess what? I just shrugged and told him that I'll look into other options.
Which brings me to a final point, which isn't really relevant to this topic, but is good advice none the less, and should be considered by everybody.
When you can, choose the people around you. I recently stopped talking to someone extremely toxic and my behaviour has significantly improved. Don't give assholes the time of your day, unless you want to vent some steam of course.
