How would you like being forced into serving someone? Don't you like the idea of being able to control the machinations of your own business? Of course not Noomi, you'd rather the government tell you whom you can and WILL serve, under pain of financial ruin.
Do you think I should be allowed to refuse to serve people who are black?
Do you think an African-American photographer should be forced to take photos of a Ku Klux Klan event?
Good question. But a photographer is actually at the occasion - like a Christian photographer at a gay wedding. That is a lot different than simply baking a cake, and not witnessing the ceremony.
I personally think it should be illegal to be a member of a racist group, anyway.
