It is a heavy claim, because it implies you can coerce others. It implies you can grab someone passing by your hypothetical room and force them to be your audience.
No. That's never been the case. Your room is open to all and people who want to listen aren't prevented from going into it.
However, I'm also not obligated to host you in a room I own. The government guarantees my freedom of association as well. You want to opine, do it in your own room, or do it in places owned by the public at large.
Your recollection of what you were supposedly thinking doesn't mean you didn't misread what was written either. If you want me to even consider your claim, you are going to need a source on it. Because, like I said, it's a heavy one.
