When "civilized society" starts banning things "for our own good", we have officially sold our souls to the Brave New World. Banning something, hiding it under the rug for now, and making future citizens ignorant of it will only cause more damage when the banned items are rediscovered.
Who decides what should be banned for society? Obviously society itself does not, for such a democratic effort would negate itself--there are at least as many people who want their truck to be accessorized (gay) as there are who don't.
For a ban to go through, we'd need to have a sort of oligarchy of "pious and morally responsible" individuals. Of course, those individuals would be hypocrites because everyone has something impure and morally irresponsible in their lives. So we would have sanctimonious aristocrats leading us in a nanny state. Didn't the Puritans try this and fail? If this were to go on, there would be persecutions for accusations of breaking code, a la the salem trials, as history is doomed to repeat itself.
Let me know when "society" is going to start banning things, so I can be ready to fight it or make my leave. No one has challenged the system since 1860, and no one has challenged the system and truly _won_ since 1776. The odds aren't good for keeping this creeping PC tyranny down, and with such odds, it is no wonder that many harbor strong doubt that America will make it to her 100th president.
