This may be true.

however, I’ve frequently been told I’m essentially undatable by men. I’m fat (I have lipedema), not young (I am 42), and have a child. Yet I have no problem finding plenty of women who are happy to date me, and have had some great times. I constantly hear about how men don’t want fat, older women with kids, yet none of the women I’m with care that much. I keep hearing women “hit the wall at 30” and after 40, forgetting about it. A lot men won’t date older women, but many women do date older men. I think on that trope men are the ones being shallow, wanting someone young while women are flexible with age there. It also creates an social scarcity, because if a man only dates younger women, then he has chopped of more than half of the dating pool, and he is competing with a lot of other men for a narrow margin. Hopefully not all men do this though.
Of course I imagine many of the women I date are also considered undesired by men. Many of them are my age, some are fat like me, and I obviously have no problem with dating other mothers. I also date trans women, which some people won’t go near. I’m glad I do though, I would really be missing out otherwise.
I guess I don’t really understand, in Herero sexual relationships people act like it’s a just a bunch of scores of who has what attractive scores, and how good someone can get. But I just go by or people who work for me. I’ve dated men too, and never had any of these weird preferences I’ve been told I’m supposed to have. My ex husband was shorter than me, and made less money than me, but we were very much in love and very happy.
I also have had dated a younger, thin, wonderful bisexual girl, the kind many men greatly desire. She wasn’t shallow either and had no problem with my fat old self (I didn’t have kids at that point).
I think people do have preferences and that’s okay. I do feel bad for many of these incels, I can tell they are sad and lonely, I think dating would be harder if I was man, I will agree. But these red pill guys seem to have a false understanding of women, they’re so admit on telling me who I am as a woman and what I want, and totally ignore the fact I actually understand myself quite well. But they won’t listen at all, which is going to further alienate them from women, and it’s quite a toxic cycle. It’s very weird. Some women are shallow and only want a few very narrow things-this is true. I recommend not going for women who are shallow, which yes, will probably be the young and beautiful. They’re probably so shallow because they are hot. But women like me, and there are lot of us, are essentially considered not even datable by men, sometimes I don’t even feel like I’m even considered a woman, but around other women, I’m considered fully datable. Even with the restriction of poly-only. I feel bad who just go for the prettiest of women, that would be very tough and dehumanizing. I have never wanted the 3-6 in a man, (oddly my current girlfriend has the 3-6, she’s over 6 foot, makes 6 figures, and is in really good shape with a great body) but the women who do, men would be good to leave alone. Go for someone less shallow, somehow I tend to find lots of women who aren’t shallow, I guess I’m just ignorant what men go through.
