Exactly. It's not rocket science. If people are not REQUIRED to listen to someone, then that person has no "right" to be heard. Hitler and Castro had a "right to be heard" as it was enforced by armed men. No one in America... yet... has a right to be heard. We listen to people who make sense, who have something new, profound, or interesting to say, but we do that willingly. None of those people, no matter how articulate or brilliant, have a right to be heard, any more than Ford making cars does not have a right to make us buy them. We listen to smart people because we WANT to, not because they have some "right" to be heard. They only have a right to speak...everything following that is based on the actual rights of others, to listen or ignore.
