Unless you refuse to bake a cake.
Full disclosure - I'm a catholic and lean Right. I agree with religious rights, etc. BUT...
I never really agreed that people should be able to refuse service such as baking a cake. What if I owned a hardware store in a small town and a same-sex couple walked in to buy supplies for their house? What if I owned the only gas station in town? Could I refuse service to same sex couples? I understand a cake isn't a necessity and most likely there are other bakers. The issue is where do you draw the line? Who decides what is a necessity and what's fair? See where I'm going with this? If anyone could refuse service based on religious reasons then I could refuse to sell someone food even if I'm the only store in town open at the time.
Honestly, as a Christian I don't get how baking is against MY religious beliefs. I'm not the one walking down the aisle, nor am I practicing same sex marriage. I'm merely not denying someone a request that I would grant to anyone else. For lack of a better way to explain this... If God doesn't want same sex couples to marry then God will deal with it in the afterlife.
