That feels mostly like a distraction to me. Here are some related HN links, nothing to do with "incels".
I recommend reading "Jaws" by Kahn and "Breath" by Nestor. Both of them mention John Mew. He was an early advocate of the harmful effects of certain orthodontic practices on breathing. Sometimes the problem doesn't show up for decades.
