Yea, spitfire your right, I'm in high school, and we get blanket punishments. If one person does wrong the whole class gets punished. For instance, we have a resource-like period for homework and seeing teachers. Now a couple of students used this period to leave the resource room saying that they had to go see so-and-so teacher. Instead they loitered in the hallway. They did this for several weeks into the school year, never ONCE getting in trouble! Then about two months later the principal enforces a strict new set of rules in which noone is allowed to leave the room unless a teacher comes and gets you from the resource room (except for piss breaks). This was due, to as she said, "students wandering in the halls". Uhhh.... why don't you just punish the people that breaks the rules instead of everyone else, dee-dee-dee?
That kind of rule only works in the military [if one person "fracks" up, the rest of the unit "fracks" up.] and has proven to be a very effective form of discipline. However, this rule doesn't work for squat in the civilian world. An individual civilian has the potential to create a habit of making everything work his/her way at the expense of other people's freedoms. Unfortunately, more and more individuals are developing this habit [especially beurocrats] and it has grown to the point where freedom of speech is in danger of being censored. This is why I consider "extreme" political correctness to be an infringment of every individual's right to free speech.
Don't get me wrong, I like political correctness; but only to an extent. For example: I understand that calling a mentally-ill person a "retard" is a very BAD idea considering the history of the word in the United States. However, I will draw the line against political correctness if it grows to the point where common sense is also in danger of becoming extinct.
