I think trying to win those people may be a better strategy in the long term. People feeling left out are angry, and if the train stops and they ride together, they wouldn't be so anti-social. Again, "I think" (Which is more of a hope, admittedly).
People with views like these shouldn't be given oxygen with platforms that allow them to form community around horrible and hateful ideas. In my opinion they should feel left out, until they realize that it is their immoral views that make them unacceptable to larger society.
