It is pretty horrifying if said moral or religious grounds say that a business has the right to intolerance. It promotes hate and discrimination. It says that it's 'ok' to be against someone if you don't approve of a lifestyle choice that affects no one negatively. Especially when you're promoting one that says that you have inherent rights over others because you were told to believe something that they don't.
I don't think I should be refused service by somebody because they don't like the fact that I don't believe in their god. The door is opened on that kind of discrimination if you let others say that it's alright to say no and look down on people based on other sexual or gender factors.
I'm not claiming the Democrats don't do this. You said this, not me. Let it be said. Tu quoque fallacies won't fly here.
Your notions of what promotes hate and discrimination are irrelevant to the rights of business owners. If you don't like what they say don't buy from them. It is "ok" for them to be against a lifestyle choice or whatever because the freedom to think and say things, regardless of "muh feelings", is a constitutional right. The guarantee to cake themed however you want from any bakery isn't a constitutional right. There are many things a business could do that should legally qualify as unfair discrimination. Not baking a cake for a gay wedding because of religious beliefs isn't one of them.
It's one thing if you just walk into a bakery and order a cake but if walk through the door, tip your fedora, request a cake that looks like Richard Dawkins and saying "god sucks", they should be able to tell you no.
I suggest the Christian cake vendors bite the bullet and make the damn cake. And stop going into the bakery business. And maybe learn a thing or two about civilization and their universal reality.
Granted, I'm not much for ideological extremism either, and it goes both ways of course.
Civilization and universal reality dictate that a business has no choice in what events it will cater for? According to whom? Do the owners of these businesses not have rights of their own? Government has no role in telling a private business to serve for an event they'd rather not. It's a complete waste of time better spent on fixing real problems.
Seems you're rather clearly on one ideological extreme when you suggest that all Christian bakers get out of the business.
