I can't read this post, but you need to go to the source it's quoting:
https://youtu.be/9ZDTBqb8Juo?t=1611 -- Cofnas is joking with the interviewer. He doesn't think such a position exists or would ever exist, it's a joke and/or outrage bait for clipping up. His actual views, the ones that got him fired, are ugly enough.
His actual motivation is completely straightforward: R E V E N G E
He got sacked from Emmanuel College (part of University of Cambridge) in 2024 due to the public uproar against his published blog posts, and in particular the college's reasoning was that his blogpost was a "rejection of diversity, equity, and inclusion". That's right, Emmanuel College explicitly requires you accept DEI or they'll sack you. So Cofnas's motivation is to:
1) get back at the University of Cambridge for sacking him
2) bring DEI into disrepute and get everyone to reject it
You then have to ask the more pertinent question. Why did Cofnas know to look for plagiarism in Arday's work? SOMEONE AT CAMBRIDGE TOLD HIM TO.
The anonymous member of faculty did so because they knew all about Arday's dubious academic output and did not like that the university had brushed it under the carpet.
Both Arday and his employer had numerous opportunities to be honest and open about it, but they suppressed it and called the police and lawyers on good-faith academics and journalists.
So what's Cambridge University's motivation for doing that? Simple: they wanted to protect their "star professor" who appears so often on TV, radio and in the press, to hide the fact that only 75 out of the 6180 academics at Cambridge are black, and they are actually a bastion of white upper-class privilege. Even though they know he's a plagiarist and a fabulist, and if everyone learned that truth, it'd bring all academics and universities into disrepute.
This tragedy was entirely of their own making. I look forward to seeing Cambridge University properly investigated over this.
