ACLU used to defend KKK’s right to march and express. Liberals used to be extremely pro free speech even reaching across the spectrum in the bowels of right-wing extremism to protect their rights.
The fact of the matter is that speech and generally liberty is one generation away from being dismantled and eroded. If the newer generation wants to abolish it and institute an authoritarian style censorship, they’ll get an American equivalent of CCP censorship, but through proxy of corporations. All buttons and knobs are in place with Big Tech. It just needs following.
The fall of speech rights in the west is a recent phenomenon and America appears to be the last bastion fighting for it. COVID was the last straw that broke camel’s back for places like Canada and New Zealand.
