If beauty was the only metric of attractiveness or likeability, sure. Except that incels are not celibate because they're ugly, they're celibate because they're convinced that women don't want them because of their looks. That thinking makes them entitled people with an overall terrible personality. That's why they can't get laid.

Men have it much, much, easier in the beauty standards department then women. If a man can't get laid his looks have relatively little to do with it. There are fat short dudes out there absolutely killing it in the romance world. Personality, empathy, and good attitude are worth their weight in gold.

Women are expected to not be fat, but men are expected to be tall. It's easy to hit the gym, but height is impossible to change. It's also socially acceptable for women to fake good looks by wearing makeup and high heels, but for men, it's not socially acceptable. So yeah, women have it much easier beauty standards.
