Not necessarily. I understand where you’re coming from, but again, it’s still their private property despite being a commercial entity that is open to the public. They’ve forfeited certain liberties such as the ability to discriminate or not work with health regulations, sure, however they’re not complete public accommodations — as in they’re officially funded through tax money and, even in part, controlled by the government. This is why I would agree if the cases was, say, Milo Y and public colleges where it is public and is a threat to his free speech. Sanders, however, is not in a public place. Just like Ben Shapiro wasn’t on a public college when one of his talks was cancelled and they were within their rights to do so. So long as they didn’t break those discrimination laws, they can politely ask anyone to leave for nearly any reason that’s not illegal.
