You would have a point, but...
--not all kids are equal in school. Some of the jocks and older kids literally *grow up* in body some half a decade before their minds begin to catch up. This is especially a problem in a young man's gym class where your larger and often more aggressive students more or less "own" the others and the P.E. coach encourages it all in the name of "teamwork".
--P.E. class in the United States could be so much better than this, both in terms of not letting the Non-Jock Majority go to waste (and getting them in shape) and in terms of teaching them some *skills* of a real-world self-defense sort to keep the worst bullying from becoming a damn shootout courtesy of endless and mostly unstopped torment.
I mean, really, I had some issues growing up, and still have some today, but I am GLAD that when I was a kid, I *was* allowed to try to fight back against the bullies I had to deal with (long story short, my father was a psycho and threatened to beat me *even worse* if I didn't fight, and teachers by and large got this one). If I hadn't been allowed to at least try to resist and fight back, chances are I *would* have ended up in prison or dead courtesy of going *even crazier*, ok?
--You are talking to someone who was a class clown for 3 years in High School as a survival mechanism. Did it work? Not even half the time. Really. So why do *you* want bullied kids to make a *joke* out of their suffering? What's in it for YOU? A laugh? Maybe a sneaky *reward* for being a jerk, or maybe you're just too *weak* and soft-hearted to *stand up for someone* when they are being picked on and driven half-crazy.....
Really. Why do you want kids who are picked on to NOT seek help? Why DO you want them to isolate themselves? Sounds kinda shady and predatory to me bub. :p
In short, based on my experiences being bullied *at school* and abused *at home* I have to say it. What the "dumb thing" to do here is to "suck it down" and "laugh it up" as you suggest.
That is only appeasement. That is only sucking up to those who hurt you and giving them further license to do so.
What the smart thing to do is....find an adult who is clearly on your side (not just any adult....there are ways to find allies, and it can be taught), and tell that person, and let that person *stand up for you to other adults* on the issue.
And then....if your parents or P.E. coach won't give you the skills you need to deal with the over-grown Cavemen who attack you for giggles and shizz, find someone who knows how to fight, and either learn from them or at least *make alliances so you have use of their ability*.
Really....I mean, what other choice is there? Curl up in a ball and die? Be the dog who gets beat until you snap and try shooting up the whole school? Really.
Just my plug nickel, having dealt with a lot of violence in school and at home--really, on a basic level the bullying didn't end until my 20s when I *got out* and headed to college. :)
