The trick of this person's story IMO isn't so much that cooking snobs are bad or that any way of cooking is good or bad. It's that the author wants to be a cooking snob themselves. They're upset that the made-up qualifications of being a cooking snob don't accommodate their disabilities. Okay yeah that's unfair, but the whole point of snobbery is to be unfair to people and consider yourself better than them. You don't have a lot of credibility if you want to be a snob yourself but are upset that you can't meet the qualifications. Instead of shaming the snob group for not accommodating you, let go of your desire to be a snob yourself. Once you do that, their opinions don't matter to you anymore and you aren't constantly searching for signs that some random stranger approves or doesn't approve of how you cook, and sometimes perceiving them even when they aren't there.

Cook however you damn well feel like. Your food tasting good to you and whoever else you're feeding is all that matters, not the opinions of internet strangers on Twitter about how you did it.

Once you really understand things and let go, you can see snobbery as kind of a joke, a fun game to play, instead of something super serious and important. I think all of the people who have strong opinions on, say, Vi vs Emacs are older and mature enough to not take it too seriously anymore, so any "flamewars" about it nowadays feel more like people joking around than an actual battle.
