I wouldn't say it's entirely propaganda, since I've seen shy guys who are good-looking; women really like them and see them as interesting and mysterious, but it doesn't go beyond that. I'd say not all women are willing to do 70% of the work when flirting with a shy "cute" guy. Usually, only a very dominant and crazy Becky do that. I've never seen a shy, handsome guy with a beach Stacy.
