Exactly. If as a business owner you believe you can make enough profit to stay in business by rejecting sweeping sections of society then you get to reject that business. If people who are in your "approved customer" groups decide to boycott you because they dislike your stance then you get to deal with that loss of profit as well. But if you think you can still survive, have at it. It's really not all that different to a business deciding to rent space heaters in Arizona during June - they are free to attempt to make a profit but may find themselves unsuccessful.
