I totally agree it's about learning and participating at that age. But then why not just have the Autistic kid wrestle his weight and compete and be involved? It rarely the circumstances in a situation that get it heated it's almost always the way the situation is presented and handled. Honestly they probably had no idea the kid was even autistic until they were told about it anyway. So that in thier mind at the time of the dispute( Not even knowing he was autistic) was probably irrelevant.
Also as a side not my sister in law works with autistic kids at heartspring in Wichita and usually they hate being touched and go crazy like their being smothered.So why then would you decide to expose a kid like that to wrestling? Just some thoughts
