It's not "running away".  It's "not running into a feminist buzz-saw".  If a man can make just as much money or more without subjecting himself to the feminist gauntlet he runs in today's universities, then why on earth shouldn't he?  By going into traditionally-male skilled trades he'll be making far more than his female peers far sooner, with no debt.  That beats a false rape accusation any day.  That's something feminism hasn't realized yet: when you disincentivize men, they'll withdraw.  It's part of our masculine nature not to invest in something that's not going to pay off.
