My father had schizophrenia, and my wife has tourettes.

It's a completely different scenario. Someone with tourrettes knows what just happened. They're probably deathly embarrassed and apologetic.

In the schizophrenic case, they're being aggressive, hurtful, belligerent -- no one is obligated to sit through that. There's no reasoning with them, there's not even a discussion happening.
