One distinction I would like to make is that between lack of romantic interest vs hatred. For example I work with a young woman who is engaged and not romantically interested in me, but she is still nice, polite, friendly, easy to work with, and always happy to help. Even though she is not romantically interested in me, I do not sense any hatred from her. On the other hand, if I go to a grocery store or fast food place, young women employees always have a bitch-face when taking my order. This is the default facial expression any woman has when interacting with me. Maybe if I am at a sit-down restaurant the waitress might smile because she wants a tip. But then as she walks away I see her smile instantly turn into a scowl, reflecting her true emotions.
The vast majority of women I interact with seem to not only not romantically interested in me, but in addition they are actively hateful towards me. I understand the lack of attraction, but why are they hateful? I find it really repugnant when young women are rude bitches to men they are not attracted to. Young women should be required to be nice to everyone, even ugly guys. Get off your high horse. You might have more sexual selection power, but it doesn't mean you are better.
