It isn't.First of all, that was a statement to liberals in general, not just about this case. But on this case, liberals want gays to have something straights don't have. They are saying they should be able to government marry the same sex. I would not say that if they went to the legislature, but they are going to the courts. The courts rule on literal, they do not make law legally.
Democrats are demanding they make law because liberals don't like the law as it's written and they can't be bothered to do it the right way. It's not a sweeping statement that gay marriage is better than straight marriage, it is referring to how they are going about it. We don't like that law, the courts need to fix the law. That is how they think they are superior. They don't have to follow the course the rest of us do.
If the majority goes left, game over, they win. If they majority does not go left, then the courts fix it. Game over, they win.
We are following the proper course. When your civil rights are being violated, you get to petition the courts.
Straights can marry the same sex too so your "gays get special rights" is pathetic.
You still can't name a single gay who has different rights than they would if they were straight.
Using the same logic blacks and whites had the same right to marry under anti interracial marriage laws.
I don't want to marry a man just as Mildred Loving didn't want to marry a black man. How is discrimination based on gender different than race?
Again, the civil rights violation manifests when a couple eligible to participate in marriage is indeed disallowed to enter into a marriage contract because of the composition of that couple, whether the couple is interracial or same-sex makes no difference, where either couple's right to equal protection of the law is violated.
