I think you're really off base. A quick search about what Williams has said about censorship on the right seems to undermine your one non-weiss example [1]. There were more than a hundred signatories from across a fairly wide political spectrum (and the letter itself was anti-Trump). The handful of signatories that I follow have squarely denounced right wing censoriousness - I'm open to hearing that I'm seeing a non-representative sample, but you didn't provide any useful info on that front.
