I don't want to hang out with this autistic dude on my birthday
Why do you not want to hang out with this person?
He's an idiot and I'm not interested in hanging out with him during my birthday.
It's rude to not want to hang out with autistic people. But if it's your birthday, it's your choice on who you want to hang out with.
I said he is autistic idiot. He's just a loser and I don't need loser hanging out with me during my birthday.
You shouldn't be calling autistic people idiots. That's a terrible attitude to have towards the autistic community.
