I think you are assuming your reality is actual reality though, why is it politically correct to say that ALL men are created equal, should it be amended to say All straight men are created equal?
I have yet to see one solid fact why giving gay couples equal rights is a bad idea, I have heard moral reasons which in reality are purely subjective and for many more an indication of closed minded dogma, I have heard religious reasons which are no different in fact I find it ironic that an institution that preaches tolerance is the primary institute leading the segregation charge.
It is a lifestyle that I simply don't understand and as such creeps me out but so do thousands of lifestyle choices around the world from religious to political and yet because it does not affect me it does not concern me, I still stand by the argument that:
1) Churches should be allowed to marry who ever they like.
2) Gays should be allowed to marry who ever they like but not where ever they like, see point 1.
3) It should all be recognised by the state as legal.
