Only the precursor to "cancelling or book banning."
The weird and dangerous thing about authoritarianism is that it has no built in limitation. Every time it succeeds in gaining some form of social control, it wants more. There is no built in concept of when it has gained enough, or too much, control. We are seeing the abject failure of authoritarianism to limit itself in the republican party these days, to the degree of absurdity. But it happens among democrats and liberals, too. They impose their authority to gain some well-meaning social control and they immediately want more. Without any question as to how much is too much. Or about who is being overlooked or imposed upon by their quest for ever more "righteousness".
Of course we don't want smut magazines available to grade schoolers. So we use our "authorities" to keep them out of their hands. Yet it never seems to stop there when that goal is achieved. There is always the next well-meaning self-righteous cause to use the imposition of authority on, to "correct". And no one ever seems to ask themselves if their cause is really all that righteous or their solutions really all that necessary. Or what other unforseen damage might result from this "correction". They just trudge on blindly.
Because as the government sanctioned killer in the movie "The Outlaw Josey Whales" said: "Their ain't no end to doing good".
