The key point, again, is that left and right define free speech differently. Democrats are now advocating limits on political speech, which has nothing to do with yelling fire falsely in a theater. But here's Sen. Schumer, in a late-night Senate debate on the Democrats' "DISCLOSE Act". See Rob Bluey, at Hot Air, "Schumer calls for “limits on First Amendment rights” during Senate debate."
Bluey has the transcript at the link.
I personally don't remember any instance where the First Amendment was argued to protect equality, but that's the rationale Schumer's proposing, that limits on free speech are needed to protect equality. Only radical progressive make such arguments. They make them when the attempt to shut down conservative speech. So I can't stress enough how it behooves those of us on the right to fight the progressive anti-speech effort with everything we've got. A successful push to amend the First Amendment is the real threat to equality, the equality of an open marketplace for political speech.
