You can’t discriminate based on sex or race, you can based on personality.
1. You probably don't have many friends or
2. Your friends are not very diverse
Outside, in the real world, I can sit and have a very pleasant conversation on TV shows or Lisp interpreters with someone with terrible ideas or belief which are inconsequential to the matter at hand and are not part of the conversation. I can sit for a beer with childhood acquaintances that I know are racist, bigots or generally idiots, because we're talking about something else than the things I know we don't see eye to eye. And that's fine.
It is frightening that we're forgetting how real people outside the Internet are, behave and can get along in all their complexity.
Where did I say that?

Good for you. We're multinational company with thousands of employees, I personally been witness to situations where incompatibility in views caused issues during work. In my free time, with my childhood acquaintances I can talk about anything, during work with my colleagues I want to have productive workday - not arguing about current flavor of racism or whoever-knows-what's opinions about anarchy.
Again I know it's not black and white and everyone has different red lines. If someone treats killing baby mammals as their favorite form of entertainment I probably can't work with them.
Actually my gender and race are much more "me" than my blog, cause I might change my opinions and my blog no longer reflects my internal "states".
