You suggested it wasn't delusion if men are telling them they love it. I then said men will gas up chicks they are trying to fukk. You acknowledged that men do this to women of all shapes. In other words, you acknowledge yourself that men saying they love it is most likely game they are running which means that them saying they love it is irrelevant.
Men will fukk girls they find mildly attractive (not just talking about fat girls, could be ugly girls too) in the right circumstances. If a guy meets an ugly girl he feels he could fukk, he might gas her up, might fukk her, might get used to fukking her and eventually wife her because of other intangibles she brings to the table. Now from the beginning he's been telling her she's fine, she's the most beautiful, no one compares to her, etc. Should she suddenly pretty because she got wifed?
