On the contrary, Simba. It does indeed need an explanation because it's actually pretty damn considerate. It would be one less thing the admins would have to worry about.
I don't mind if you disagree with my opinions, but if you're going to dismiss something I say, please explain why you don't agree with me. You don't have to, but it helps me understand you better. I don't like when I write out my thoughts about something and try to make people understand my opinions, only to be told I'm wrong and not be told why someone thinks that.
