Yes I do.

I think this is the real joke

I personally find it funny at face-value but the joke does get ruined for me because, as you say, it's just a veil for certain beliefs. I used to enjoy a lot more of Aronson's work until I realized he was just strawmanning the views he disagreed with. I had previously thought it was just good-natured ribbing.

For an actual funny (and not so "blah blah SJWs ruining everything") version of this joke, the tv show Atlanta does a much more entertaining version of it, you can find it if you search "transracial".

It's ruined because you don't like Scott Adams but the Atlanta clip (which is good, thanks for sharing) is funny because you like Donald Glover? I like both spins on the joke as well as both comedians.

I actually don’t know Donald Glover’s political views, but I do know Scott Adams’s political views because he’s very outspoken about them and he keeps complaining about “cancel culture”. In general, I’m pretty tired of comedians making low-effort jokes and then going on about how they’re going to be cancelled because they’re “so edgy” - it’s just trying to get a rise out of people. That’s what Adams seems to be trying to do here. He also posted a bunch of tweets about how he was going to get cancelled for that strip and it just made me roll my eyes.

To be fair, it's Dilbert. This is a comic strip from a bygone era of observational "humor," like Garfield or Kathy.

I don't think people actually expect humor, so much as "I find something in this comic strip that I recognize as similar to something I've encountered elsewhere."
