I am attempting to compile a 'Top 10' style list of instances of censorship, blatant or covert, perhaps for publication. To qualify open discussion of a subject must have been actively suppressed by the media, institutions of power or governments.
Covid dissent probably ranks at #1 for me, followed by questioning the primacy of 'gender' over biological sex at #2.
Censorship is, in my opinion, a sign of right wing supremacy, particularly when exercised by the left.
Any more?
