An important part of libertarianism (which forms the premise of the very creation of USA), is that you cannot use your liberty (or free speech) to deny others their right to exercise liberty (or free speech). When someone advocates for censorship using free speech or taking away liberty 🗽 from everyone whom he disagrees with, he’s effectively doing the same thing. This kind of behaviour must be strictly prosecuted and the person should be deported. If you fail to do this, USA 🇺🇸 may no longer exist.
