How does serving people who you believe are sinning go against your religion? Wouldn't you have to stop serving everyone instead of just discriminating against gays? Everyone is sinner.
From a Christian standpoint, very, very true. As a Christian, sometimes we are hypocrites. I don't know why so many of us, or any other religion that has sinning in it, act like being gay is so worse than any other sin. A sin is a sin, they aren't any worse than normal people.
As for that cake business fiasco, that's a different story. The Bible states marriage is between a man and a women, so to serve a gay couple is going directly against their beliefs. So in this instance, not serving a couple due to their sexuality is understandable.
The Bible also says sex is for marriage not before marriage. and you shouldn't cheat on your mate(adultery). those sins are directly against Christian beliefs, yet those businesses have no problem serving those people. So why is it understandable to discriminate against gays but not other sexual sinners?
