explaining my conduct

Dear Professor Turner,
I'd like to apologize for walking out of your class this morning. I meant no disrespect. I consider your lectures to be generally stimulating and useful.
This morning I felt compelled to be a jerk and run off at the mouth, and since you get enough grief elsewhere I thought I would try not to give you any more. I suppose I have this unfortunate tendency to debate the validity of some of your points and to do so in your class which is an inappropriate venue. I would like to have an opportunity to discuss with you some concerns I have with the Zinn text. I don't think it's a piece without merit by any means, butsince its original publication in 1980 it may have changed with regards to its relevance to contemporary thinking. What I see as dangerous is that critical theory, which started out as the notion that it was incumbent5 upon us to challenge orthodoxy has itself become the new orthodoxy. I find it disturbing that Zinn seems to have no cumpunction about condemning people out of hand because they were on the wrong side of politics or the class divide. It's not that historical revisionism is necessarily unhelpful or dangerous, but the rigidity of the school of thought represented by a peoples history is alarming to me. If I argue with you in class, I'm playing devils advocate perhaps, but I am doing so out of these conderns I have.
I know you're very busy and a great many people depend on you for a great number of things, but I would appreciate it if you could find time do discuss this and related matters, perhaps during your office hours.
I'd like to reiterate my apology for walking out of your lecture, and for having been disruptive in the past. I know you have a difficult job to do, and I regret having interfered with the carrying out of your duties. Please forgive me, and if you could see your way to answering this email, that would be cool too.

Kind regards,
