Why do we censor in Schools?

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.

As people grow older, their ideas change. Right now, it's easy for us to see the logic against censorship, but maybe forty years later, you and I too will forget about the dangers of having censorship and it may seem like the logical idea, as it's the easiest to do. Censoring is simply less time consuming, an immediate fix to a situations that may arise from not censoring. Instead of actually sitting down to explain why the behavior is "bad" and why the consequence is appropriate, simply just deny it's existence.

It may be obvious to us now why censoring is damaging in the long run, but as we grow older, like your beggar scenario, we tend to forget about these things, much like how we forget about childhood experiences.

As our logic changes, our memories fade. Without the link of logic, memories cannot be recalled, and even if we go back and look at a video of ourselves in infancy, we may still not be able to remember fully because we are unable to remember what thoughts exactly occurred in our minds. (For example, we can't recall why Peek-a-Boo was so fun.) Our minds would have blocked the memory.

It's unfortunate but it happens. It's not necessarily that parents have so much pride that they're willing to go out of their way to protect their reputations among their own children. (Heck, that sounds like such strange logic.) I'm pretty sure all (nonabusive) parents want what's best for their children.
