Similarly, since I oppose virtually all censorship I accept the legal existence of content that I consider reprehensible. It would be true that I tolerate bad content, even though I might be against it and protest the message.
I tolerate bad content because the likely harm from censorship is greater than the potential harm from the content. With business discrimination, the harm from the conduct is greater than the harm from the laws against it. In fact, most businesses benefitted from the end of legal discrimination.
