Sara, those men didn't have to go along with it but most men are cowards when it comes to defending women against the sexual harassment of other men. There's a code they don't want to break because they've been taught since they were children that they are better than and more important than women and girls. Obviously, not every man buys into this lie but the majority do because they're brainwashed as children. So when it comes time for them as adults to show ethical behavior, they lack the modeling of other men, as well as the courage to do the right thing. Most men are cowards.
