Is it wrong that I get irritated with people who don't have common sense?

I try not to.

I mean it's not their fault they're dumb.

I'm not trying to be mean either, but if you can't think about things like that...you're kinda dumb...

Ok, I guess I am being mean

It's just so aggravating to me that people can't use common sense on things that are obvious.

I guess I'm just an asshole, but I already knew that :)
