I think the post you were responding to was just nit-picking the logic that illegal == immoral (or wrong). I don't see anything in that post that states what you are railing against here.

No, definitely not everyone. For starters, it should be obvious the GP would exclude "those who believe gay marriage is morally wrong".

But in particular, I am especially wary of the "personal morals and ethics" of people making broad generalizations like you just did.

Fortunately, I know somebody who's perfectly entitled to enforce his personal morals right back at you. And yeah, I am aware that you could do the same thing, but you also appear to believe that to do so would make you a bad person. So it's your choice, really: Submit, Be Good, or Be Bad.

To enforce the obviously right ones, sure. A la Rosa Parks.
