Nobody is born a White Supremacist. It is not a protected class.
No one is born married. The florist had no problem serving gays, she just didn't want to be involved in a gay marriage - which was against her religious beliefs. Race is a protected class and white supremacists are all about race.
This really is something which needs to be considered. Equal protection means just that. It has to be equal. If you can deny services to someone because you don't like "those people" then they can as well.
Exactly. Those who think Christian bakers should be able to discriminate regarding gay weddings need to accept that gay bakers should be able to return the favor for Christian customers.
