How am I wrong? Can a business owner who holds a business license refuse to serve any group he/she dislikes? What groups are included in that? Jews? Catholics? Blacks? Women? Muslims?The fact they did reject serving a same sex wedding proves Quest wrong. Religious and artistic freedom trump PC regulations and forcing Christians to attend same sex wedding ceremonies or any other religious service.
If you love freedom, keep marriage one man and one woman.
Or is it only gay couples?
You might as well say that we need to keep interracial marriage illegal, to protect the religious rights of business owners to discriminate against those couples.
We don't harm a group of hardworking law-abiding Americans, simply to protect those who would illegally discriminate against them based on religion. If you are unhappy with that, I suggest moving to a country that is government by religious law.
But I can tell you that many places under religious law aren't that friendly to Christians, either.
