The gays don’t care about getting married, they can already have all of the benefits, thereof.
This is about the state sanctifying and normalizing homosexual behavior.
It goes even deep that that. There is a real, palapable contempt for everything Christian or even American (Christianity embodied in a society) that the homosexual liberals foster deep within their being. It's not just about unfettered acceptance through normalization, but about destroying Christian morality by any means. Normalization is just a means to this end.
