Contrary to your hyperbolistic nonsense, you can do business with whomever you please. If you want to refuse to accept a job offer from a gay man, you are free to do so for that very reason. Corporations and organizations, however, may be under some different restrictions, but those are *not* applicable to the freedoms of individual humans.
In other words, a businessman doesn't have human rights? Used to be they were allowed to reject employees or clients for any reason. Now they can't. We've lost that freedom.
