It has everything to do with the subject at hand.

HBS graduates ~900 people per year from the MBA program. The fact that many end up in positions of power is only partly related to the HBS experience. Given that there are more graduates from this school than any other top business school (as it's older than the others, too), it's not surprising that you find some bad eggs. The fact that you have a list representing 0.01% of the graduates as evil (and I don't even concede all your names as true criminals/wrongdoers) shouldn't be enough to indict all HBS grads.

Perhaps you've traveled overseas and felt the injustice of being scorned as an American for actions you took no part in, or perhaps even opposed.
