Yes.
I have labored this on multiple threads and shown my workings.
And I am not clever like Heather Mac Donald, Douglas Murray, Andrew Doyle, Sam Harris etc.
Mmm. So, just to make sure that I'm not being completely unfair here...
I looked up Heather Mac Donald and the first thing I got was... "Why female leaders should be presumed guilty unless proven innocent:"
Hmm.
Andrew Doyle - "Is vandalising a Pride flag really a hate crime?"
Hard questions, eh?
If you're judging by the person, I'm pretty sure that you could do a lot better. Note, it would be very, very OT to address either of those more in depth here if you happen not to see what's wrong with them, so I won't.
To be clear, I will agree that you have put in a bit of effort in opposing DEI. I've not been paying pretty much attention to more dedicated DEI threads, so I can't say much about how well you've made a case in those. If threads like this one are to be the guide, though, your workings are very unsatisfactory for what you're trying to do with them. The general Anti-DEI case is problematic, though, all around.
When it comes to businesses, for example, the more recent DEI push arose after a bunch of businesses faced lawsuits because they were discriminating against women and minorities. That caused a shift in practices for risk avoidance reasons and PR efforts to play that up for business reasons. More recently, there have been a bunch of anti-DEI lawsuits, which has changed the calculus on how best to try to avoid risks. Personally, I find anti-discrimination lawsuits that pretty much come down to "You're trying to help the poor, but competent, and not the rich, but incompetent? How dare you! Lawsuit time!" to be far, far more deserving of being called evil, though, than DEI does. Meritocracy is a fine goal! DEI is just one part of efforts to make Meritocracy actually happen, though, in a real sense, rather than a caricature of Meritocracy.
You've raised the duck-rabbit illusion. That certainly is an example of something interesting. It's just not actually a good description of what's actually in play here. On the one hand, you have people fighting for meaningful equality. On the other hand, you have the people who have a long history of seeking to oppress others fighting back against the people fighting against their ongoing oppression. Nothing that you've said has even remotely addressed or refuted this basic truth about DEI and the anti-DEI efforts, so far as I've seen, which makes your efforts to call people fighting for actual equality "exquisitely evil" a bad joke.
With that said, calling Harris a DEI hire insultingly is, to put it kindly and offer immense benefit of the doubt, deeply misguided. Especially if you try to compare her to Trump. Harris is a woman, but competent and would fairly certainly hire in line with merit. Trump is a man, but incompetent. He's also been very, very clear, both in practice and promise, that he will actively work to destroy meritocracy. If you actually cared about meritocracy, you should be praying that Trump loses and loses horribly.
