I know there are a lot of folks on here that think it's not discriminatory, but if it walks like a duck and quacks like a duck, well...you know how that goes.
Take this sentence for instance:
I will not serve you because you are [blank].
Start inserting words: black, white, handicapped, gay, lesbian, asian, conservative, liberal, Christian, muslim, jewish, athiest, a Patriots fan, an Eagles fan.
Now, for those of you that have read this far, Let's talk about Jesus Christ. Jesus loves everyone. Jesus hung out with the thieves, hookers, dissidents, tax collectors, and worse. Jesus was perfect, and Jesus did not discriminate.
There are Old Testament teachings that prohibit interracial marriage, and in those days, interracial was a lot less easy to define than black and white. Additionally, theft and adultery were illegal according to the Old Testament, yet Jesus sought out these people.
If we really want to go there, then we can also talk about what Jesus said about Judgement, but I think I've said enough.
Now, that said, if the lesbian couple was expecting the actual baker to come to the wedding and denounce her faith, then that's a different story.
You make the same mistake that the left makes.
This particular issue is NOT about serving somebody because orf what they are. I'm sure the bakery would gladly serve homos.
What they are refusing to serve is "gay marriage." Which is an entirely different concept than discriminating against a person.
It would be the same as saying that because I refuse to bake you a Hitler Nazi cake, I am discriminating against you because you are white. See the difference?
Jesus told the adulterous woman to stop sinning. Jesus called Matthew out of the wicked actions he was doing as a tax collector. Jesus changed the life of Zaccheus so that he stopped cheating people.
Jesus did not applaud, endorse, or promote sin.
Besides, the first amendment applies.
