I disagree that I have a duty to teach them, but I do agree that you shouldn't silence them. You can ignore them if you want.
The world is screwed up because everyone looks only to their bellies and their genitals - that's all. The foundation of consumption is based on this and everything evil is as well. I would like for people to think before they act; if they did so, bellies and genitals would no longer represent a factor.
