Freedom of speech means *freedom* of speech and freedom of the press is literally freedom to publish whatever you want. You do not have any right to muzzle other people because you don't like what they're saying, even when what they're saying is delusional.
The reasons for this are self-evident: If there were laws against "disinformation", they can just as easily be weaponized against information by those in charge. Our founders knew this too: The British considered the rebelling colonies to be just as delusional as you consider the insurrectionists.
Speech is inherently subjective. When you cede control of it to the government, it's just a matter of time until those restrictions are used against you.
Instead of trying to silence those you disagree with, speak against them. Allow people to hear both sides of the story and make their own decisions. That's how a truly free society operates.
