I will share my two cents on it.

Gay happens. Whether or not a particular religion believes it is a sin, it still happens. We can not condemn a person for not adhering to our own religious beliefs. We should just be thankful that in a world that is quickly erasing God form the planet that we are allowed to have any beliefs at all. I am not saying i think gay is great. All i can do is remain neutral on it. Let the gays face their maker for judgement and answer for their sins as I will have to answer for my own.
You may not like it, but what can you do?? The only objection to gayness is that it is a sin, but it is not for politicians to accept or deny anything based upon an individual or group's personal beliefs. That is the world we live in. Jews dont eat pork, but you dont see them trying to get it banned for the rest of us.
What I am opposed to would be a religion flip flopping on beliefs just to not offend. If a church has made it well known for millennia that they abhor homosexuality, i would have no respect for them whatsoever if they suddenly throw open their doors and start asking God to bless the holy union. Now marriage by a justice of the peace is acceptable to me.
As for the whole subject of gayness in general, it is a thing that is a bit gross to me if i do too much visualizing, lol, but it is not a thing that deserves such attention. Let people be. Stop persecuting people for loving, and focus on stopping the people that are hating. I say this because when i face my judgement, i would rather say that i loved too many and accepted too many sinners as beautiful children of God, than to say i persecuted, judged and shamed people for being about as imperfect as i am.
