It's sugarcoated to hell though. It's literally TRP "lift and fix your game" bullshit. What they don't realize though is that you can't just "become NT", it doesn't work like that. Therapy doesn't work because it's just empty talking and it relies on you realizing yourself and magically fixing your problems (problems that almost as if weren't there in the first place?). Other option is to start taking hard drugs (SSRIs and antidepressants) but those can cause side-effects too and might not work. And even if you did, you have a LOT to catch up. You can't just go from 0 to social king, you'd have to be the funniest most charming guy alive.
Looks on the other hand define how others treat you. If you look like shit then people will treat you like shit. Add the fact that you're friendless and that makes it even more OK because nobody will defend you or feel bad. Good looking guys simply don't get bullied because they're good looking.
Let's face it, those "average guys" you see getting laid all the time probably had tons of friends from childhood and probably didn't get bullied or ostracized, probably because they were average. Incels on the other hand probably got bullied to hell and were isolated, which leads to P E R M A N E N T mental damage. No amount of talking or pills will reverse that.
