thank you by the typographical correction. with respect to your point 3,  "mathematics and politics do not mix, but create nice names anyway", I recommend two books about it (no comments):

Book 1:  Taylor, Alan D., and Allison M. Pacelli. Mathematics and politics: strategy, voting, power, and proof. Springer Science & Business Media, 2008.

Book 2: Weil, André. Souvenirs d'apprentissage. Vol. 6. Birkhäuser, 2017.

*Factual* is not *fatal*. And yes, it's exactly what Max says. It was perfectly clear in the context of that discussion:

On a side note, the fate of the term got complicated already before Labour lost three elections in a row (2010, 2015, 2017). The explanation of the name was still there in the draft citeseer version of "Elimination with a Motive", Section 3:

http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.23.6292&rep=rep1&type=pdf

but it seems to have completely disappeared from the final version of the paper published in TYPES 2000, which uses simply the name "heterogeneous equality":

https://link.springer.com/chapter/10.1007%2F3-540-45842-5_13

Perhaps the referees made him remove it.  But, 1) as Mikhail Bulgakov put it so memorably, manuscripts don't burn, 2) you cannot rewrite history and 3) mathematics and politics do not mix, but create nice names anyway.

thank you. because it is not a mathematical error, I think that I will read the thesis. I do not care too much about politics.

I think it was sarcasm. The factual error is that McBride's thesis says "John Major was the LAST ever leader of the Conservative Party to be Prime Minister (1990 to 1997) of the United Kingdom" (emphasis mine) which is clearly not relevant to the contributions of the thesis.

If I'm not wrong, I read that Conor McBride's thesis contains fatal errors in the comment 21 November 2012 at 13:11 of the discussion : https://homotopytypetheory.org/2012/11/21/on-heterogeneous-equality/#comment-2537

I quote this comment (I don't know if it is sarcasm) :

And also, strip Connor of his PhD since his thesis contains factual errors.

Its a reference to John Major: https://coq.inria.fr/library/Coq.Logic.JMeq.html

Best,
