I can't BE a kink, only be INTO it. You wouldn't say someone who indulges in buttsecks is an Anal. Though some of them can be. The terminology is what throws me off most I think. I guess since it's such a 'popular' fetish and the fact that gay was already and adjective, it easily transitioned into a description of a person rather than a description of a kink. Do I think we need to rename the entire debate? Yes. The debate is about Same-Sex Marriage, as some people already call it, and it's dealing with (hopefully) two people connecting on a far deeper level than a sexual one.
But, I'm rambling and someone's probably going to take issue with what I've written so I'm gonna stop for now.
