for or against gay marriage?

personally, I am in support of it.
I honestly dont get why anyone cares enough to be against it and act as if marriage is only right if its between a man and women.
With last i heard the divorce rate being close to 70% of marriages now, Straight people have done a good job ruining marriages on their own.
If gay people wanna be miserable like the rest of those married, who is anyone to deny them that?
