Private organizations have the right to regulate themselves as long as they are within the law and their contractual obligations. They don't have to be fair or even consistent and I don't have a problem with them being able to do this as long as they are a private organization. Even though I tend to disagree with a lot of the decisions as they make when it comes to kicking people off the air as it relates to what they say may be offensive.
I'm not interested in outlawing fascists thoughts and people being able to express their fascist views whether they come from the Right or Left. As long as they aren't able to pass those views and policies through law. Because that of course would be against the First Amendment even if it does offend some people. Because again we have Freedom of Speech and the First Amendment and I having my right to argue against fascism and the political correctness movement from the Far-Left. Or the moral majority movement or whatever from the Far-Right.
