You're missing the point. A community can also be fukked up. Do you really think a fukked up community will teach children right from wrong?
Yet as I stated, this isn't just about the children. This is about what media adults can consume. If an adult can't tell the difference between right and wrong, I'm sorry but that's on them and their parents. Other adults shouldn't have to suffer their foolishness.
Actually, it does. What a government decides to make law and illegal will fundamentally change and define its nature. If it decides to ban media that is against government policies... would you be for that? There are plenty of governments around the world that bans speech and expression on the grounds of morality, ethics, etc. Those places aren't something you and I would think are decent or moral.
I'm sceptical of all governments. I'm not an anarchist or libertarian. However, I'm for limited government. It's a hard principle to maintain but it must do so.
Most people don't.
If you really want to reduce any crime, then it requires proper policing and enforcement of already established laws. For example, there are already laws against murder and theft. Just enforce those laws properly with better policing.
Banning media that 'promotes' illegality is nothing more than jingling keys to distract the governed that the government has failed in its duty.
