To straight people pledging not to get married until same sex marriage is legally recognised: please, don't do it for me.
If you want to get married or don't want to get married, that's okay. If you don't want to get married because you believe marriage is tainted by being only available to certain people, I understand that. If you don't want to get married as an individual protest: well I think it's ineffectual and I actually find it irritating, but that's your right, but don't pretend you're doing it for those who never asked you to do it.
I confess I don't really understand the whole idea of "I'm going to sacrifice things I have that other people can't". If we lived by that maxim I'd never go to the movies, never use transport, never eat a nice meal, never wear new clothes. The world's set up that some people have things other's can't: we can and should fight that, but we can't just opt out of it.
If you want to support queer rights, ask some queer people what they want you to do. Maybe some will say "don't get married" - we're not exactly a monolith, but I'm confident they'd be a minority. If you asked me, I'd ask for you to help me paste some posters, for $50 towards printing (maybe you could opt for cheaper chair covers), to like and share a facebook page, to challenge transphobia and homophobia where you see it, to join a march, to tell any young people close to you that it is okay, it really is okay. You can do one or more of those and still get married - see, much less of an imposition on your life.
Don't assume that our priorities are the same as yours, or what you assume yours would be. Don't assume that we all have the same priority. Don't assume that we want to get married, or that we don't.
Don't assume there's some clear dividing line between equality and oppression, when some queer people can marry now and some relationships will almost certainly be ineligible for state recognition when same sex marriage is recognised, and marriage rights won't change so many things anyway.
If you're in a situation where marriage carries important practical benefits, where it is necessary for you to obtain healthcare or immigration status, please don't screw with your life like that. Not only do I not want to see that happen to you, I'd honestly rather be putting my energy into activism, rather than worrying about the needless 'sacrifice' you've made.
These types of actions, however well intentioned, always feel like an appropriation. Actions that make it all about the straight couple. Actions that we're supposed to feel grateful for, that we're supposed to appreciate, that we're supposed to owe you something for, when most of us never wanted them in the first place.
Enjoy your marriage, your civil union, your handfasting, your pissup, your relationship unaccompanied by an event, whatever. I'll be wishing you well; if I know you well enough I'll be there, taking advantage of the free food. And when you get back from your honeymoon, or recover from your hangover: well, I could use some help on a poster run...
