I'm not sure how a reasonable comparison of authoritarian behavior seemingly assigns more weight to random Wikipedia contributors lumped together as "leftists" compared to the literal government currently controlled by the right that is routinely threatening to pull FCC licenses for critical speech among other intentionally speech chilling threats.

I'd say the pendulum has already swung the other way, while swinging much, much further and more openly than nebulous mob demands for "cancel culture", over zealous Twitter moderation of hate speech or whatever else the previous go-to examples for the left were. Before 2025 showed what a truly authoritarian anti-free speech policy looks like when wielded by those with actual legal power and zero shame.
