So anybody could attend? It doesn't sound very private. People were excluded -- no problem with that. Skin color alone seems to be the criteria -- big problem with that.
For the record, I defend the rights of people to be bigots. I also defend -- and exercise -- the right to call them such.
Based on your logic, I'm a bigot. The other night I had a party at my house for a number of friends. None of my neighbor friends, however, were invited: the black couple across the street (so now I'm a racist), the gay couple two doors down (so now I'm a homophobe), the German lady down the street (so now I'm a xenophobe).
It never occurred to me that I was being a bigot, "excluding" my neighbor friends simply by including only my other friends. So next time I'll invite the whole town, but I'll have to get a bigger house first. What's important, though, is that I have you to defend my right to be a bigot. Thanks, I guess.
