This is not even remotely true. If an establishment refuses service based on someone’s race, sex, religion, or sexual orientation (in many states) they are in violation of the law and face fines or even eventually the forced closure of the business. This has been the case in our country for most or all of your lifetime.Wait, so getting a cake baked for you is a right?
Oh, its not? Time to move on to another establishment that will sell you a cake, or why not just make one yourself? Bakers are free to sell, or not sell, any of their wares to anyone they want. Patrons are free to utilize, or not, any services offered by an establishment.
You may remember something called the civil rights movement which showed why these laws are important.
