I'm going to kick out an autistic kid from my movie theater
Why do you want to kick him out?
I'm want to observe and learn from what people do after I do that.
You shouldn't treat him poorly just because of his condition. You need to be more patient and treat him well.
I think I will learn if I know him better.
It is good that you want to know him better to understand how to treat him better. It is not good to treat them badly just because you don't know them well or because you want to see what other people do.
