This page is dedicated to anti-people. I say people, because if you hate a type of person, Asian, African, or French, you'b be dubbed racist. I don't hate one type of people, I hate them all. But thats not the point. I may be an asshole for doing so, but shit, I'm being honest, and people always say honesty is the best policy.
Extreme circumstances call for extreme measures.
I don't normally swear, but if someone is so dense, you have to make your point bluntly. Then maybe they'll leave you alone. Or if you want to be proper and keep your composure, just say what comes to your mind. Hopefully people will start to get the idea. You may lose friends after a while, but the ones you have left, you can trust.
