Honestly... who cares? It's so weird to me when people make up hypotheticals just for the sake of getting angry about them. No Democrat is likely to say this about a Republican, so why bother entertaining the idea?
That's also kind of the point, no?
If you want to split hairs, no not really, they're two separate points. If he said "no Democrat would make a joke about Liz Cheney having a penis" I wouldn't have disagreed. Harry's post read more like "wah look at how my side is subject to different standards" which, like, yes dude we're all aware because we lived through the Trump administration. I don't think one really needs to conjure up self-deflating hypotheticals to explain why this kind of joke is dumb.
Ok, so your point as I understand it is essentially "yes we already know Republicans are loathsome, crude, hypocritical, and subject to their own set of standards that they never hold others to, but it's boring to keep pointing it out." I would disagree. If we don't keep pointing it out and reminding ourselves of this fact, we will all soon become accustomed to it, and eventually tolerant of it.
