I've raised two sons and a daughter largely by staying out of their way when it came to their interests, except to encourage them to pursue their own wholeheartedly.  Our oldest son showed an interest in music quite early on so I decided Dad had better walk him through blues, rock 'n roll and start teaching him Keith Richards riffs.  He just sort of shrugged and walked away.  Now he's a successful jazz percussionist...lesson learned!  
But while I would never have made him take ballet to discourage "macho" behaviour, my wife and I talk about all sorts of "social issues" around the dinner table,  and I think for that reason our kids have grown up with pretty savvy ideas about various kinds of stereotypes from both ends of the political spectrum.  
I do find that many comments here are a bit histrionic. There are some provocative thought here, and the world won't end because McLaren has said things that strike people as eccentric.
