No, but the juxtaposition of "footballers' antiracist gestures must be silenced" with "We must intervene to prevent Big Tech from declining to broadcast racism" in the rhetoric of prominent mainstream US conservatives is a pretty good indication that the longstanding tradition they are actually defending isn't "free speech"...

That only works if your frame for literally everything is racism.

Kaepernick kneeling during the pledge of allegiance can only parse as an antiracist gesture if the thing being disrespected (flag/country) is presumed to be intrinsically racist, i.e. it's accusing the whole country of racism. There are a lot of non-racist patriots who would take offense to that. The answer still shouldn't be censorship, but calling any opposition racism is accepting the very premise that the people opposed to the gesture are opposing it over.

Moreover, the implication that everyone who has been canceled was a racist is contrary to evidence unless you're making some heavy tribalist assumptions about anything vaguely conservative automatically implying racism.

And you're still not addressing the original point, which was that the left going around canceling people over speech is inconsistent with freedom of speech. Nothing anyone on the right does can make that untrue.
