Did you feel the same way when years before Oregon used the same PA law to fine a business over 300K for refusing to serve a Christian couple?
To be honest, I never heard of that.
Actually I would have supported their right to refuse service on religious grounds. Sometimes what is right, feels wrong.
The First Amendment makes it clear that the government should place no limits on anyone's right to practice their religion.
If, for the sake of argument, a Muslim owned business refused service to a Christian based on some tenet of his faith, I would stand behind him.
Kind of like the quote mis-attributed to Voltaire: "I disapprove of what you say, but I will defend to the death your right to say it"
