no that is incorrect.
sheltering kids from love, violence, and swear words does not prevent them from abusing and misunderstanding these things.
that is LITERALLY choosing to NOT teach a child. so the result WILL be bad.
plus it is impossible to not expose a kid to swearing in the world. you must be living under a rock if you believe that for 1 second.
the fact is, telling kids to do or not do things isn't teaching. even kids are human beings that can better learn through explanation and logic and reasoning.
this is why most parents fail. posting rules is not teaching.
