It's an insincere argument that government censorship is equivalent to public shaming or canceling (or however you want to describe the "left"'s actions here). When the government does it, it's authoritarian. When a group of people do it, it's freedom of expression. There's a discussion to be had about how it may go too far or be extrajudicial (people being fired for non criminal activity), but it's markedly different from the force of the government.

This isn't some even handed application of the FCC's policies against hate speech (if that's how one cares to describe Kimmel's comments) or misinformation (is there even such a policy?).

You don't have to look far to see this is politically motivated: just this week a Fox host suggested that the homeless should just be exterminated. I don't believe the FCC has threatened Fox's broadcast license in an attempt to influence Fox to fire him

Like most arguments online it’s a bunch of people with little to know knowledge of the actual facts filling in whatever details they want with their own opinions then getting hysterical over the hypothetical implications.

I for one choose not to participate.
