How do you handle the bigots in your life?

[Mermaid]

My brother and his wife are right wing, tea-party type racists, so it's not an option to avoid them completely. I love them both very much, so it can be difficult. It takes a lot of diplomacy, and sometimes when push comes to shove, directness, to completely avoid any conversational territory that crosses into the danger zone. My brother seems to love to talk about it, and I often have to tell him to stop and why this is necessary.
