no, it isn't. It is 100% intending to suggest that anyone saying anything about racism is just virtue signaling. That is what comedic caricatures are for. They mock behavior by exaggeration and over simplification in order to discredit a viewpoint or people.
You're ascribing intent that is not at all evident in the video.
It's a video of a silly person doing something more silly than most real people ever would, in order to promote how virtuous she is, which isn't helping anyone. That's all it is. That's the caricature.
There's no part of it that suggests that all mention of racism is virtue signaling. That's YOUR thought. Whether or not you agree with it, that originated with YOU, not the video.
So you admit that it is a caricature intended to mock anti-racist activists as nothing but virtue singling attention seekers, but think it is nothing more despite that being exactly what theater has used it for for the entirety of the Human existence. cool, cool.
Whilst I do agree that The Onion often takes something and runs with it to create an extreme situation hoping to bump into humour...
....they're still making choices about what aspects to run with. They could have just as easily taken a Ben Shapiro type conservative and made them run away with being I don't know, so unpolitically correct that they become politically correct again. I don't know, that's just off the top of my head, but the point is they are choosing who they mock.
...and they used to choose more substantial issues.
Because you can't exaggerate something to make it ridiculous when it's already so ridiculous.
Bad faith communicators like him already take their outrageous rhetoric and false conclusions farther than any funny parody would, effectively making them impossible to humorously satirize.
I never claimed any such thing, nor would I ever. Do you ever say anything that's NOT about a ridiculous strawman you concocted in your mostly empty head?
And note the "already exaggerated past the point of self-parody" their entire point is in fact exactly that anti-racists are nothing but self aggrandizing attention seekers.
