If a business-owner's "ideals" are to discriminate against the classes included in the public accommodations laws, then he should find another business. He is obviously unable to conduct his business in the way that the law requires.
Or, let him deal with the consequences of being a bigot and a scofflaw.
Or find another country more compatible with religious beliefs that are antithetical to Americanism and its bedrock tenets.
It's like someone who can't resist stealing money working in a bank.
To make the analogy even more apt, let's add that his religion requires him to steal money. Does it matter if he objects to being fired and/or arrested for so doing, or calls it religious persecution?
Maybe the boundaries of what is meant by freedom of religion need to be discussed and specified more clearly.I would grant the religious the right to believe what they like, pray if they like, read their Bibles if they like, wear religious symbols if they like, ask others if they'd like to hear about their faith, and congregate in their private spaces to fellowship, sing hymns, listen to a sermon, etc.. Perhaps there would be more if I thought about it more.
But just about everything else that the religious claim for themselves as their rights because of their beliefs can still be called illegal or actionable. The state makes the rules, not the individual adherent or his church.
