When you spend 12+ formative years telling kids to sit down, be quiet and do nothing but listen to authority or else, they aren't going to somehow come out of it as stellar, well-rounded debaters.
They will, of course, project how they were treated onto others, by holding deeply ingrained beliefs such as, "When someone is being disruptive they need to be punished."
It is the primary inspiration for the movie "The Matrix". When Neo takes the disk from the hacker at the beginning he actually puts it in a hollowed out version of this book.
Anyway Post-Modernism has lots of fascinating points and sub-topics and skilled writers, however if you read too much into it you can quickly become a very annoying person.
Great stuff, but read in caution and in moderation.
You hit the nail on the head, and it isn't limited to this memo. We have a serious intolerance problem in this country that goes far beyond Nazis and racists. Over the last 25 years our culture has warped to the point where opposing viewpoints are considered by many to be offensive. Kids have been raised in an environment where they are told that they (and their opinions) are always worthy of respect (no matter how uninformed or ignorant those opinions might be). Those who show insufficient respect (in the eyes of the person being "disrespected") are seen as hateful aggressors who must be attacked or silenced. In today's society, many people (especially young people) don't want vigorous debate between those of opposing views. They don't want to live in a marketplace of ideas where logic, morality, and the ability and willingness to articulate and defend your beliefs in a public forum are valued. These younger people have been conditioned to appeal to authority when they are offended or their beliefs are challenged, rather than answer the bell and debate the merit (or lack of merit) in an idea or statement.
Unfortunately this withering of public discourse is a bellwether for authoritarianism. You need look no farther than the recent outcry against the ACLU for their defense of free speech. There are very dark days ahead.
