Blacks were beaten regularly by police. I don't see that happening to gays in this country.
I do see it happening in Russia. Hence the comment that equating the inability to marry a person of the same gender in some states to getting hosed down by a firetruck for being black aren't even close to being the same. Hence why its insulting to those who were there.
Blacks are STILL regularly beaten by police, however that has changed somewhat. Now the police just beat/stun/kill/anally search EVERYONE, so that's a kind of equality, I guess.
