This kid is a freedom fighter!
Though I will say that my sister actually did this once, publicly, in front of an audience and everything. She didn't receive any consequence for it. So thankfully, this isn't an epidemic or anything, though still very disturbing in this specific case.
Freedom Fighter my foot. That being said, the Supreme Court long ago prohibited mandatory participation in the Pledge of Allegiance in
West Virginia State Board of Education v. Barnette. The issue isn't that the kid didn't stand for the flag. The issue is that this kid, who likely had underlying emotional problems, was provoked needlessly by a teacher who didn't get it. That, coupled with the utterly abysmal staff in Florida's Public Schools who are unprepared to deal with kids with problems.
