 I think of it in simple terms. If you had an old-fashioned village in America, and in the town square there was a big blackboard up there with a bunch of chalk, and you said anybody can come up and write anything they want on the blackboard, disgusting things, profane things, whatever you want, but you're a platform. And if you're going to be open to all, do you then have to say, if we're open to all, then we can't exclude conservative speech or other kinds of speech like that?
