So the KKK was not a problem towards equality of people of a darker complexion? Good to know that all black people were suddenly absolutely equal and were treated equally when those laws were repealed and could be "free" all over the place without, you know, fear. Oh wait.
You can make all the laws about gay marriage you want, if the gay person in question has to hide his sexuality for career reasons or for fear of reprisals, and he doesn't dare marry, that doens't help at all.
It's the same thing in reverse of the gun argument: making laws about it won't suddenly change the reality. It's the reality that matters, the laws should be obvious extensions of the people's will. Saying "as long as there's no law prohibiting it, we're all good" is odd.
Remind me where I said social pressure was not a problem. Also, the KKK isn't exactly social pressure, but I'll take your point and include them.
I already acknowledged there are problems for people when pressured by social factors, so I don't feel like we disagree that someone hiding their sexuality for fear of discrimination is bad.
I think the disagreement is about "oppression." The state can pass laws to enforce the illegality of, say, homosexuality, or the second-class role of people from certain racial backgrounds: that to me is oppression. That the KKK exists is not, as they can't set up systematised cruel and exclusive treatment of people, even though
their own treatment of people be cruel and exclusive. When it comes to lynching, vandalism, threats, graffiti, we've gone past 'social pressure' and we have a group terrorising another, breaking laws.
It's also the case that you said "social pressure is
just as much an oppression as a law." The part I've emphasised I find remarkable: it isn't. If there is no law prohibiting homosexuality, it is tremendously safer, freer, and more likely to change hearts and minds to say "I am gay," than in a society where it is illegal to be gay, even if the majority of people dislike homosexuals. This is because people will not fear the state by associating with you; perhaps they may be less fearful/ashamed of coming out themselves. It would be something that would be safe, even defended by the law, rather than crushed by it.
