There are lot of unintelligent posters here and its impossible to tell if its a 12 year-old trying to be edgy or a grown adult with issues.

It's not even a question of the views themselves. If expressed in a structured, intelligent fashion even reprehensible views can form part of a constructive dialogue. The above kind of low effort posturings are nothing more than random brain farts with no real thought behind them and, as such, not worth responding to. Call them out and based on how they respond, if they seem like a complete waste just block them.
