Nasty mix of half-truths and misleading statements.
First off, an "Incel" simply means, involuntary celibate. All of the so called "misogyny" that happens is added on or tacked on.
Technically true but Incel is now associated with the misogyny too heavily to ignore it.
Looks matter, along with your entire bodily concept, much more then personality or any other external factor.
Over stating the case. Yes looks matter more then most women would say, particularly for just walking up and talking to them at a bar. Personality and other factors matter a lot for building an actual stable relationship.
Women just have incredibly high standards due to them knowing about genetic potential and superior men.
Both men and women suffer from excessively high standards. When both sides expect to find somebody of equal or better looks there is actually only a very narrow range that matches and that depends on both sides agreeing on what their range is.
I think worse is the expectation that relations will just work. In reality it takes a fair bit of work from both sides to build a good relationship and there will be missteps along the way.
