Instead of censorship, perhaps we should codify universally acceptable ideas and put them into a book. This book would be distributed to everyone that wants one and once a week we would gather and read a portion of it together and receive guidance from an expert on the subject. Over time this should lead to a more virtuous society.
I think this would be preferable to the clumsy "whack-a-mole" system we currently use to silence unacceptable ideas.
