This is an attitude it's very hard to deal with, and you find it all over the place, even among people who absolutely have no excuse given their educational background. I do think it's more common with people who, in school, rarely had to deal with much honestly-meant critique - i.e. people who just got good/great grades, and where their errors tended to be technical rather than errors of thinking. Especially if they went to university and then studied a technical/science subject, or if an arts one, one you could get by on by simply learning a lot of other people's opinions and being able to explain them. So you get someone who has got into their 20s, and barely anyone has seriously critiqued them, and thus the first time someone actually does, they're horribly offended.
Or maybe that's all a pile of nonsense I've built lol.
But I do notice that nerdy people are way more into "critique = hate" than arty people, with the exception of people who have come into art with little formal training (if we look at authors, every author I've ever seen take a "critique = hate" attitude has an educational background that isn't creative writing or the like).
