Actually, that is a valid answer. You can express your disagreement verbally, even. I don't care. Make your business a religious business that only caters to the people you want. Don't hold your business to be open to the public. That means you can't serve Hindus, atheists, etc., but only those who you deem to be worthy of your service "in keeping with your principles." In so doing, you make less money, but you get the satisfaction of knowing that you haven't compromised your beliefs.
