Is it wrong to hate the existence of autistic people?
Don't you think hate is a bit of a strong word to use there?
Yeah, I guess "I don't like" would be a better word to use
People who are autistic didn't ask to be that way. Hating them for something out of their control is wrong. Stop doing that now.
Does it even matter? They're too dumb to understand what I'm saying anyway.
Let me address that misconception first and tell you that there are many autistic people who understand exactly what you just said. Either way again, they didn't choose to be autistic and you hating them for something they had no control over is rude and wrong. Try to be more understanding if you can.
