Also, not everyone can just get a nose job and be attractive magically.
I think many people in the incel community don't understand how far showering, dressing well, and working out will get them. Its much better than complaining without any action. Also, I see many of them complaining about not dating "10s" yet never bother to look at people at their level.
This is not really true. At least in the observable, online incel communities. Incels talk a lot about "-maxxing"[1]; looksmaxxing (improving appearance), gymmaxxing (improving physique), surgerymaxxing, moneymaxxing, therapymaxxing, ... you get the point.
The most common advice (showering, better clothes) is also a meme within the communities, like the "Just take a shower, bro" meme.
But also, dating is usually many to many type of activity. Sure maybe marriage is one to one. But you can enjoy dating even if it does not result in marriage, multiple times with multiple people.
I dated a very obese, unattractive girl before. Ultimately it was her selfishness and failure to understand reciprocity in a relationship, that made me not want to see her anymore. Still was an interesting experience.
1) She started to work out regularly
2) She got a nose job
3) Buys well fitting designer clothes
4) Spends money on hair and nails
5) Wears gold jewelry and hand bags.
All of these complement her appearance.
When some girls go to so much effort to look good. While the incel guy does nothing to improve their appearance. And often does the opposite. Terrible diet and sometimes even terrible hygenie. Yet expects to date a girl like this.
