It's ridiculous, and it doesn't stop at what you're describing... from suspensions and expulsions for kids being kids to denying kids the opportunity to play dodgeball or have holiday parties (two of the things that essentially everyone I know of looked forward to at that age).
People are overprotective of their kids - they want to do what is "right" but the problem is that most people don't really know what "right" is. The problem is perpetuated by people watching Katie Couric report about some study performed by a so-called expert says that if your child was forced to square dance in gym class, he or she is 10% more likely to be a millionaire, and suddenly you have 100 parents calling a school demanding square dancing as a gym activity. The thing is that each child is different, and each child responds differently to situations and activities. There's no "right" thing to do because what helps one kid could very well hurt another.
The thing that people tend to forget is how the views of supposed "experts" have changed through the years. These experts have told teachers and schools to do this and that because it will "make it better" for our education system. Where has it gotten us? We're lagging behind in education. Children are coddled tattle tales nowadays rather than learning how to defend themselves. The amount of exposure given to these topics has only made this worse (in my opinion).
Think about it - what are some of the animals that you fear the most? Sharks are probably one of the first to come to a lot of peoples minds, right? You know what kills more people every year than sharks? Cows. Seriously. Similarly, statistically speaking, nuclear power is actually the SAFEST form of energy available. You read that right. Friggin windmills kill more people every year than nuclear energy! Yet, you hear the words nuclear reactor, and you immediately think of death and mutants. Because of 1 (completely avoidable) incident in Russia, and 1 minor mishap that realistically did no damage whatsoever in the US.
The problem is that the media takes an isolated incident, and blows it way out of proportion. Not only that, but it doesn't let you forget about it either. Think of the big thing right now - cyber bullying. You see stories like the one in my source - headline is "Teens Arrested in Cyber-Bullying." for sending lewd, threatening texts. Read the story, and you'd think they were picking on one kid from school who was unable to defend himself.
If you research the story, you find out it was members of a rival high school football team trash-talking a kid on the other team a week before they play.
This was in Austin - a city of 750,000 people, and it made the news. As someone who's played football through the D-1 college level, trust me, you would hear much worse things from the guy lining up in front of you - and that's someone you're within an arms reach of! You see tons of similar headlines - Twitter Fight Leads to Murder! Did it? Because those two idiots hated each other long before they started tweeting one another about it.
My point is that people panic about EVERYTHING, and they demand immediate attention about any problem that is "sweeping the country." If the example that you gave became a newstory, could you imagine the headlines? "Millions of boys across America Sexually Assault their Female Classmates!" How quick do you think that sort of behavior would be squashed? Wouldn't you agree that it's not only an over reaction, but somewhat of a deception by the media?
The knee jerk reactions due to some study with skeptical results need to stop - basically we need to better TEST new theories in small markets first rather than suddenly banning dodgeball across America because it made some fat kid feel like a loser. To that kids parents - how about rather than suing the school for "making my kid feel depressed" how about you take the damn cupcake out of his hand, kick his *** outside, and let the dog chase him around for an hour every day? Maybe then he'd be better at sports, and it'd actually HELP his confidence rather than hurt it.
Of course, that's not going to happen because as society, we're expected to adjust to accomodate people rather than allowing people to adjust to accomodate society. Thus we throw out knee-jerk reaction policies which can seriously change the way our children learn to grow and socialize - policies that could hurt our kids in the longrun. Of course, there's really no way to know what the longterm impacts would be without extensive studying, which people don't allow - they want results now, and sadly our kids are the ones who could end up missing out in the long run.
