I mean you'd have to have like pretty fucking terrible social skills if you think asking a girls weight or focusing on it is a good idea during your first proper interactions with her. Larger women are still - surprise! - women, so yknow maybe they don't like people basically just reducing them to a number and a size? Maybe, like most people, they want to get to know people and want people to get to know them because they have personalities? Like I don't get dudes when they say they don't understand the idea of fetishizing or whatever, cause it's really simple: there's nothin wrong with havin a certain taste in women, but to reduce them to that fetish and nothing more, well that would make anyone feel dirty.
