"Everything wrong with using a people's past exclusion as a reason to exclude others"
I have to agree that this is a huge problem, especially in modern English Depts. It's fine to focus on minority lit, but it's ridiculous to not even bother talking about people like Hemmingway, Fitzgerald, etc, because they are "dead white men". Happens alot...totally skewered perspective.
I disagree with you about teachers not promoting some sort of liberal idealogy, though. Going back to school in this administration, I have heard more liberal propoganda shoved down my throat than I can even detail. 3 out of the four or five classes I take a semseter have a teacher with some sort of political bent that they throw in, and they do in off the cuff comments, not by injecting it into the actual lecture. I dunno how prominent that was when you went to college but it's huge now (at least here, at least under Bush) and I'm told that it was pretty big in the Vietnam era.
Wether or not that "brainwashing" works is questionable; most people get their politics from their parents, anyways. You see kids taking a wide assortment of "mulit-cultural" this and that and they still spew out "Last Sons of Kypton" and "kyke" at parties. So whatever.
