To get philosphical for moment, the guy says that they are keeping him out, with the implication that his stuff is good, and only not getting in becaue of prejudice. I don't know enough about coding to judge, but Musashi, the swordsman of the 1600's (and some 1500's) once said, As you do one thing, so you do 10,000. Actually, I assume he said it in Japanese, but, whatever. 一事万事
(Ichi ji, ban ji)
This guy is an anti vaxer, which indicates that he tends to ignore common scientific knowledge for unproven pop and rather stupid theories--those of you in the US, where measles is making a comeback because of similar ignorance know how dangerous this can be. .
So, I wonder if it's a matter of him having the same attitude of ignoring what some experienced people say to go his own way--in other words, going about it as he does his vaccination beliefs. And I wonder if *that's* what his problem is, that the xorg people are ignoring him the same way legitimate scientists would ignore his anti vax beliefs.
