I've taken a couple Ethnic Studies classes in college, one being Mexican-American culture. While the subject matter was interesting, each teacher I had did try to teach their own agenda. NOW, this goes for teachers of American history, as well.
I had ONE good History teacher who taught the good, the bad, and the ugly....and I thanked him for that.
Fact of the matter is, we don't need a bunch of classes like that being taught by folks with their own agendas. I've always said, "If you want to learn about some shit, do your research...'cause a teacher will teach you what they want you to know".
I don't give a crap either way, but I think these kids should understand knowledge is in their own hands...and they will rarely find a teacher who will teach them what they SHOULD know.
