ETA: since we're assigning blame, does that mean we at least found common ground in agreeing Gen Y males seem to go out of their way to avoid conflict? Because that was my larger point.
Don't at all want to have the other part of the discussion here ... but I'd agree with the above and say women are just as bad. It's a generational thing (BTW, is Gen Y the same as the so-called Millenials?) ... and that is why they love tech like FB and Twitter. It can keep so much conflict away. You don't want anyone to push you on your world (or World) view? Simply cocoon yourself in a clique where everyone knows your name and will egg you on.
Personally, I think conflict is quite healthy. Yelling, arguing, cursing people out, making them cry (occasionally!) isn't necessarily a bad thing. Passive aggressive BS is much less healthy and it doesn't allow one to mature normally in society.
