I understand your sentiment but this isn't going to work. You cannot possibly curate the worlds information to the set you approve of as safe for other people.

I understand your sentiment but this isn't going to work. You cannot possibly curate the worlds information to the set you approve of as safe for other people. You will only drive this stuff underground and make people justifiably angry and suspicious about your motives. Much better to build up trust by being honest, reasonable and listening to people without patronizing. That still will not work 100% but it will work better than this patronizing nonsense.
