You are quite right that teenagers believe rules are meant to be broken. (I agree with them!) In reality, a major trait of the Leftist machine is to punish that independence by using every "zero-tolerance" nanny-state measure they can dream-up -- if not in some genocidal dictatorship then in latte-fueled PTA meetings.
The only "rebellion" liberals allow comes in the form of petty self-denigration. Tattoos, piercings, drinking and smoking. Only this list of defiance occurs "rules or no rules, man!"... and we all think that we've won some great prize when we get away with it! All other dissenting expression is treated as thought-crime or hate-crime, quickly thwarted by pop-culture and policies of tolerance, multiculturalism, etc.
The youths in baggy jeans and crooked caps are thoroughly convinced that they are the first persons in history to "act out". In reality, they are made a walking spectacle of conformity - tools molded by insidious leaders who wish to kill Americanism... that is, what ever small amount is left in our kids by age 5.
Or in the case of one brilliant engineer, by age 29.
TEE HEE!
