This is the opposite of truth. No loser or average man feels entitled to anything.
ah. Yes. Wrong. Incel culture is based EXACTLY around the fact that plain, average or downright ugly men, who may or may not be fat, skinny, under developed, bald whatever have the RIGHT to date women who look like supermodels, and only those. They will never in a billion years date a woman who is too fat, too thin, too old, too ugly, too whatever totally made up criteria the Incel sets.
Dating apps are the epitome of judging a book by the cover so it is no wonder people use make up, filters, old photos, faked photos whatever, because unless someone finds you attractive on first glance - swipe, you're gone. without even reading the bio. It is a fact of life and it is really no different than the Debs going to Queen Charlotte's ball then launching on the season to get a husband (titles, mothers and money played a part there, too, to be fair) or the, frankly, cattle market that was Tiffany's on a Saturday night in the late 70s/early 80s. You had to make an effort to look good (to whom? for girls, often it would be other girls as well as the blokes, for men? those who bothered probably pretty much the same)
And then there is the whole thing of using make up as a shield. Most of my male colleagues don't notice beyond "that's very red" but i do wear make up to work and when i need to bring my fierce, über-competent self to work, it is Red Lipstick that i use as a shield.
Some people don't mind makeup, some do, some love it, most have an opinion that varies according to what they're doing, who they're looking at and where they are.
