If TRP is to believed (and correct me if I'm wrong) women are not attractive over 25 (or, if they're being nice, 30) but at that point men may deign to stay with them if they've already been evilly ensnared into marriage. Therefore all men are fighting for a very tiny subset of women and deliberately choosing to ignore the rest, because they aren't attracted. Even within the ages of 16-25, there are plenty of women who are too fat, too ugly or who have kids and are also untouchable to men. This could, I suppose, be attributed to biology so in that sense it's "justified".

Similarly, women are only attracted to the top 20% of men, so much like the men, most women are fighting for a small subset of high quality men for commitment, while deliberately ignoring the rest because they aren't attracted. While men may begrudgingly stay with a woman after she expires at 30, a woman may also begrudgingly choose to marry a man who isn't in the top 20% once she realizes she won't get one in the top 20%. Interestingly, I'd venture that the proportion of hot 16-25-year-olds is less than 20% of the female population, but for argument's sake let's call it even. Women's selectiveness can also be biological, because women are programmed to want the best genes for their offspring.

This said, why is it hypergamous and shallow when women have ridiculous standards, but merely biological when men do? Isn't it biological and human nature in both instances? Is there any way we can all agree that everyone is just shallow? On the other end of the spectrum, some women will argue it's shallow for men to have these preferences, but for women, it's just "refusing to settle". Isn't it just entirely the same thing, tweaked slightly for gender?

Also, I know most guys on this sub are under 25 so it's not unusual at all for them to be attracted to women in their teens and 20s, but the general RP theory is that all men, be they 20 or 70, are repulsed by women over 30. Correct me if I'm wrong.

I do expect to hear from someone saying that if men are high-quality and getting offers from young women they shouldn't have to reject those offers in favor of taking on women their own age with baggage who they aren't attracted to. Fair enough. But if women are getting offers from the top 20% of men, why are they "scum" for doing that as well? Wouldn't anyone take a great offer if they can get it?

ETA: Some people have pointed out that for men, the pickiness is only with commitment. That's a fair point, but my point still remains because women are more picky about sex than commitment, while men are way pickier about commitment than sex. I believe men are pickier about commitment than women are about sex, but they are more open about sex than women are about commitment. So even then, it's 50-50 to me.

TL;DR I'm pretty sure both men and women are shallow.
