Anti-war or Anti-school?

If I'm one of these anti-war protesters yesterday I might get a little weary of the cause I'm fighting for when I look around and notice that 75% of the people standing around me are 18 years old or younger. I'm not saying that young adults can't be educated and have an opinion on world events, but some of these teenagers get interviewed on television and it becomes quite obvious that they have no idea why they are protesting the war except for the fact that it means they don't have to be sitting in algebra class. The media continues to toss out numbers of people attending these anti-war protests, but I don't think half of them really know why they're there.
