As I said... I disagree... and I believe the courts ultimate sided with her. The one in England as well as the one in the US. I suppose it affirms what it does and does not mean.She's not forced. Nobody's holding a gun to her head and making her bake anything.
The rule, basically, is that if you choose to sell your goods and services to the public, you have to sell them to the whole public without discriminating against certain customers.
If she doesn't like that deal, she's free to close up shop or change her offerings. "Sorry - we don't do wedding cakes any more. Just birthday cakes."
As I said: her religious freedom is intact.
Every business has to follow the law. An airline owner who thinks prayer is a substitute for preventive maintenance can't claim "religious discrimination" when the FAA says "no, you really do have to inspect your engines when we say you have to." The same principle applies.
In some sense EVERY business discriminates who they do business with. When I went to ask for a church loan, the bank said "We don't do church loans".
