There are a lot of stupid people in the world according to everybody but none of them think they are stupid and hypocritically call others stupid. If there was a good god there wouldnt be stupid people or they would at least know they are stupid and cant trust their logic and god would give them a rational person to help them be part of the solution and not part of the problem so they would do good if they wanted to so their evil wouldnt be gods fault.
What do you expect? They might not think they are stupid you are just giving an opinion. Fat people call themselves fat. Some stupid people will admit their faults, but i am assuming you are going after the ones that think they are arguing intellectually but in your mind they are dumb.
