The other day a quote from Hillary Clinton float by on this stream. It said something to the affect "Christian leaders should update their doctrine to reflect modern beliefs about gay marriage."
In my opinion this is the crux of the issue. If you believe that your religious laws are handed down by God then you are not allowed to change those laws. Those are gods laws. When some extremest screams that I should change my religious beliefs to match his he is forcing his religious beliefs.
It doesn't matter if this is some right wing nut job screaming about how doing work on the Sabbath is a sin and should be illegal or some left wing nut job screaming that I will change my definition of sin to match their definition they are both attempting to force their religious beliefs on me.
The hypocrisy that exists is deafening. We have people that wont touch a cult because "religious freedom" and that wont condemn a religion that forces child marriages because "religious freedom" don't see that they are demanding changes in other peoples religion.
