Why do we censor in Schools?

Overprotective parents feel that if children are exposed to erotic material, they're more likely to go out and perform sexual activities with other children. They feel that if children are exposed to profanity and violence, children are more likely to cuss in a public context, or resort to a weapon as soon as argument arises.

why would they feel like that? they were also kids once, they were also exposed to the same things. censorship is not protecting (and was not made to protect) the kids, its protecting their parents. all the general idea of censorship was never made for educational purposes. but its like the story about the poor guy who became rich, and forgot how he felt before and acted like an pimento. most of the kids will grow up feeling they fell a victim to censorship, and will then abuse censorship on their kids the same way their parents did, because they dont care about the past and just want to avoid embarassing situations.
