What's wrong with just ignoring a thread or individual you don't like? Sometimes people start expressing ideas and I think he or she is a total turd. Sometimes it's depressing so I go live in the real world for a while.
If they're a turd it's their problem, I'm glad I don't have to live with them. This is how I deal with people in my real life so why worry about people online I can't even see. They're probably some ten ton git with BO who has a sad life.
