If black equality and gay equality isnt similar, then how come they both have the same enemies (kkk, aryan..?

They're similar, but not the same. They might both be born the way they are, but 'gay' also has something to do with behavior. They DO choose what they'll actually do. The question of gay marriage, btw, has nothing to do with equality. The hate groups you mention are just a bunch of bullies. Bullies will go after anyone different or otherwise vulnerable. I don't even know what you mean by 'christian constructionists' and 'christian identity'. I've never heard those specific titles for groups.
