I'm going to put an autistic person back in their place
What has an autistic person ever done to you?
When he was having an episode, my father couldn't tolerate him, pushed him down the stairs and broke his arm.
You and your father are very dirty people for treating the disabled like this. They are human just like you two and should have been treated accordingly. You have no right to be around anyone else if you're just going to hurt someone.
You don't know what he did to my father...
It does not matter what he did to your father. An autistic person who is having an episode should not be pushed down the stairs. They should receive the necessary treatment to help them get through the episode.
