Because high value men will never settle for some ugly , fat, foid. The ones who are single want high value, handsome men but are too fat and/or ugly for them in the long term.
Yes some "Chad" who is addicted to sex may match and even fuck some granny, landwhale , dwarf or deformed person they meet on some low end dating app like Tinder, but that does not mean they will introduce some 70 year old grandma or a 300 lbs freak to their parents.
Walk into a Walmart or a government office. How often do you see high value men with some obese, slob by their side in real life? 90%+ of obese women are with another fat man or those low income black/hispanic men. I work with a bunch of fat pigs. All their boyfriends and husbands are either fat themselves or those low income black/Hispanic men who are making the sacrifice with a landwhale to improve their families genes by having kids with people of European ancestry.
