Go use google scholar and grab some books from Amazon on the subject, or if you are not too bothered, just read the demo versions.
Beauty has nothing to do with society and everything to do with nature. Why would you ever find someone who is fat to be attractive? Unless famine is common, you don't because it shows the person to have either health problems or poor mental health.
I have met vast numbers of girls from across this country, and also a large amount from abroad and the differences are staggering. I have fond that the only guys who do disagree have rarely or never met and talked to foreign girls thus make a judgement based on ignorance.
At least most men can claim football and maybe a few other things. It is not uncommon either for drunken male students to have debates on politics or philosophy and how to set the world right. Now how many times have you seen girls do that?
Also more male students do sports compared to girls. This is why there is a higher chance at 18-24 for a guy to be underweight then fat, and a ~35% chance for a girl to be obese
Don't get me wrong, British men are also pretty bad, just not as bad. We have not taken up putting on make-up, wearing lingerie, speaking softly etc.
Yes, somethings are social constructs, but they are very minor. Women trying to take on the role of hunter (not hunting, but raising money for food and not raising the children) has clearly failed due to the soaring rates of depression and obesity in this country. Again, if women did enjoy that lifestyle, then why do so many binge drink to forget their life?
The natural system is not needed in todays world, but we still need it as people because it is engrained into our nature and to fight it leads to all sorts of mental complications.
