It wouldn't be an issue if the religious institutions didn't try to sway politics and impose their will on me. Take same sex marriage for example. There is not a single non religious argument to be made against it.
Religious institutions are quite diversified out there. Hard to place them all in a box together. People bringing up their children in a church are quite diversified, too. The church I am affiliated with will tell gays their interpretation of the Bible regarding marriage, but will still love gays as people and treat them as such. They love them but will not lie to them.
I know a guy says GD all the time and it makes me cringe. Needless to say he is not into religion. He moved because two guys moved across the street from his house that used to kiss on each other in the front yard in front of his children; sold his house and moved. He wants his children to grow up, get married, and have grandchildren. He and his wife couldn't stand the sight of it.
I know two different people that have gay children. They love their children. What they think about their choices may very well be another thing.
There are many people cannot stand the sight of two people of the same sex showing affection for each other they think only two of the opposite sexes should be showing. People don't want to argue about it; they just don't want to have to see it. A lot of folk just never will accept it. If you want to be different, don't accuse the rest of the world for not being like you. Don't blame religion for it all; it is unfair.
Politics usually goes by the many, not the few. "They" are not trying to impose "their" will on "you". They stand for what they believe in, and let their politicians know how they feel.
Be gay if you want, but please don't be against those that see things differently. Everyone is not going to ever tell you everything is alright with your choice. I don't hate you because you are gay; I hope you don't hate me because I am religious.
