The line can be an extremely hard one to draw and changes over time such as the Civil War demonstrated when both sides quoted the Bible to prove that their view of slavery was correct.I like this post, and I think it brings up a good point, because I know how invested Christians are in their beliefs. Where is the line between freedom of religion and discrimination? I don't know, but personally I'm on the side of the guy who didn't sell his cupcakes to the gay couple in the court case. Obviously I disagree with his action, but I think he has a right to decide what type of events he gives his cakes to. In my opinion it was not discrimination, because he welcomes the gay couple to purchase anything from his store that they want, but because gay marriage is against his religious principles, he simply told them that he will not bake a cake for that particular event.
So a debate at this level does not seem very productive to me because of the strongly held and clear beliefs. My question for a Christian would be "how does your stand align with the teachings and life of Jesus especially including the Sermon on the Mount"? And if someone is a Catholic, the question would also include the messages of Pope Francis.
Part of the reason I would rather have a discussion like that is for me to understand if someone's beliefs are consistent and even handed not only for LGBT folk but for others that are sinners in their view. For example, if there's a Catholic baker and a couple comes in to get married after a divorce, would the baker make the same choice about how the couple was treated?
I might still totally disagree and think that secular law should override religious beliefs in this particular instance. But I'd rather avoid the anger and name calling if at all possible.
