I read your post all the way through, and you make some very good points. Misandrists are an extreme reaction to misogynists, and reverse discrimination violates the rule most of us learned as kids, that two wrongs don't make a right. People who attack someone based on their gender are idiots, doesn't matter whether they're men or women. But Intel pulling advertising over a bunch of griefers? Of either sex? That's equally idiotic.
Hard-core, bra-burning anti-male feminism was a reaction to the barriers women had to overcome. There's still plenty of sexism, lots of "glass ceilings" and silly assumptions related to competency for various tasks depending on your gender and stuff, but I'd like to think we're making some progress as time goes on.
And not just for women. 20% of all nurses are now men. And let me tell you, when you're ill, really ill, you don't care about the gender of the person helping you.
Since you use the term "bunch of griefers" I will assume that you have never heard of Leigh Alexander. You will be hard pressed to find a more vehement, vitriolic, and chauvinistic person even if you lived 500 years. In fact, here's a shortlist of some of the more interesting things http://theralphretort.com/game...
I especially like where she states (way back in 2010 already) that all core gamers are maladjusted losers looking for maladapted coping via games. It's hard to find a broader brush than that.
If anything, Intel pulling out is not enough.
