No. My kids don't have a severe form of autism. They are both classified as Autism-Level 1, which is the least severe.
And I didn't say I would kick them out. I said I would TURN THEM IN, to authorities, and allow the justice system to handle them. I would not pay for their lawyer. They'd get a public defendant. What happened to Josh Duggar with "the sheriff" was a sham.
People with intellectual disabilities can learn right from wrong just like anyone else. In fact, individuals with autism tend to be MORE law abiding and rule following than most. Once you teach them right from wrong, they hold onto that very strongly. They innately have a very strong sense of fairness and justice. At least my sons do, as well as all their autistic friends. Because of that, if either of my son's engaged in the absolutely abhorrent act of sexually assaulting a child, in multiple instances, to include younger siblings, you bet your behind I'd not support them at all. That behavior is not redeemable. I'd hand them over to be wards of the state, and terminate my parental rights.
