Should I talk in class?

From various court trials that our class has read these past four days, its scary to think of how little rights students have in school. In U.S history we learned about the Bill of Rights and the Constitution and all the rights that are given to citizens. But from these court cases it almost seems as if we don't have freedom of speech. In school, we simply can NOT speak our mind. As students we are vulnerable to unfair abuse(non physical) At Deerfield High School we are lucky to have nice teachers who encourage opinions and encourage us to speak our minds. But at any moment, what we say and our privacy at school can be taken away.
From these court cases we have learned that we can use our freedom of speech in any way outside of school. But, inside of school we must stay in the "boundaries". These boundaries  consist of not promoting, or what seems to be, talking about illegal actions at all. If a student disagrees with a teacher on a topic of keeping marijuana illegal, he could get in serious trouble. If a student doesn't believe that our nation should be at war and he wants people to know that he/she strongly believes that, he/she could get into a lot of trouble based on passed events and court trials. I personally think this is ridiculous! this is a free nation, is it not? Don't we have rights in our nation that we should practice, especially in school? Its not that we are just in school but also that we are teenagers, it is easy to take advantage of us. If an adult were to speak out about the war, he would not go to jail or get fined because he has rights that he is practicing. But don't and shouldn't teenagers have the same rights too? what makes us so different? because the last time i checked we are all people growing up in the same world with all of the same problems...

Examples: In the case of Tinker v. Des Moines, two kids went to school with black wrist bands on to represent that they were against the Vietnam War. Their principle heard of this and banned kids from wearing wrist bands. The Supreme Court ruled the case in favor of Tinker because it was a pieceful protest that had no threat of an outbreak of fighting or riot. the principle in this case was trying to take away these kids right to peacefully protest and freedom of speech. No matter what age, a citizen of The United States of America has all rights given to by our founding fathers.
