Most gay marriage laws do not force churches to marry homosexual individuals, so that it doesn't infringe on your rights to believe in what you want to believe in. I also assume that most gay marriages are entered into willingly by both individuals , they are not being forced into a marriage.
So why is this a problem?

Doesn't it say in the Bible that those without sin can cast the first stone? Who are we to judge other people, doesn't the final judgement fall in God's hands?
There is just too much hate in this world, and some of it comes from those who are supposed to be preaching about love.
