If someone is a visitor in your house, you can kick them out for literally any reason you want or no reason at all. No idea how this is relevant to your claim that "yelling fire in a crowded theater isn't allowed under free speech". It is legally allowed under free speech, it isn't a crime, despite what a lot of people claim. The theater might kick you out or ban you, but that has nothing to do with free speech.
