This is a really good conversation. Great personal perspectives and contributions here.
For my part, I don't mind being around people that are very different from me. (So long as they are not toxic!) Perhaps that's because I don't expect anyone else to be like me: I'm excentric and unusual so by default the whole rest of the world will be different. But I can confront when I need to and don't mind having a friendly disagreement. My prefered habit, mind you, is to search for common ground whenever possible. I am a natural mediator. At the end of the day, we are all human beings that want to be accepted and appreciated.
