I'm going to tell a possibly autistic guy at school to shut up
Why do you want to tell him to shut up?
He rubs me the wrong way, I've heard a lot of rumors about him.
It is wrong to be rude and tell people to shut up if you haven't met them before. Judging people you don't know is wrong, you wouldn't like someone to do it back to you.
I'm going to go say something bad anyway. What momma didn't give autistics a cookie?
They are probably acting rude because of their autism. Sometimes autistic people can't control how they express themselves. You should try to cut them some slack and let their odd behavior slide.
