I know where you're coming from here, and it's an argument I've seen before, and can respect in someone who applies it only to themselves as you're doing.

I have seen people who think that *anyone* bi or poly or just who strongly believes in equality in these things shouldn't marry though, and I don't think that's a good thing. Personally to me saying "I will not marry, because gay people can't marry" is not much different to saying "I will not eat, because people in Ethiopia can't eat" - it doesn't actually do anything to help the cause. You can still campaign for equal rights even if you're enjoying some of those rights yourself, and I think in the same situation that's what I'd choose to do.

It's possibly harder for you because you have the religious aspect to take into account as well, and the church seems more unforgiving on these things than the state for the most part. I hope to see civil marriages between partners of the same sex become common in my lifetime, preferably within a decade or so, I expect it will take rather longer for the church to feel the same, if ever. Mind you I don't have quite so much hope for multi-partner civil marriages, but it would be nice if people in those groupings had the same rights. I admit it's an area I feel less strongly about though.
