While I understand that there are a lot of struggles tied to being transgendered, I have always thought that same sex marriage "fixed" it, as far as being allowed to marry goes. That is, whether you're officially male or female, you can marry the person you love. And in some places, the option means if you go through sex reassignment, you don't have to divorce first. So I always thought it was beneficial to trans people.
Of course that doesn't change the struggles with getting recognised in the first place. But with same sex and opposite sex both allowed, I thought it would mean trans people had less chance of being turned down from marrying.
So I really don't understand the pet peeve, I have to say. Unless the pet peeve is that people think it will solve everything, even things that have nothing to do with marriage. Then I can see it.
