To me there needs to be a distinction between a business and a person. Sure maybe a person can't be compelled to do something against their beliefs, but a business can't claim to have beliefs and therefore can be compelled to do whatever the law requires.

And claiming religious beliefs isn't a card you can lay down anytime you want to get out of your responsibilities. I mean if I claim that paying taxes is against my religious beliefs do you think the government shouldn't be able to compel me to pay taxes simply because it's against my religious beliefs?

There's always an element of common sense judgement needed in the law which is why the people that do that are called Judges. So if in our best judgement these people simply don't like gay people and in our judgement they're just using religion as a way to trick people into thinking they're motives are based in religion and not based off on their prejudice, then what is the decision? To go along with their trickery that's using religion as an excuse? Or just tell them their arguments about religion is bullshitt and they have to get over their dislike of gay people and follow the law?

The problem here is members of Supreme court are willing to abdicate their responsibility to use judgement and go along with the obvious trickery because they share the baker's dislike for gay people.
