Do you watch South Park?
More so in the recenter episodes, they have a very strong moral. Most of the episodes are centered around some problem or belief in the US.
Sorry: they don't have a reasonable or justifed moral. If they do, the proposed solution is stupid or unreasoned. Take, for example, their multitues of insults on religion. They can make fun of them all they want, but they're not proving anything by doing so.
Let me explain Satire to you. The creators of South Park take an issue to the extreme, even ridiculing it. By ridiculing it, they force people to think about it. The point of most episodes is to get people to think of issues.
For example, the "Me and my future self" episode takes parents' unwillingness to talk to their children about drugs/alcohol to the extreme by showing the parents hiring somebody to pretend to have come back for the past. The moral isn't "You shouldn't hire an actor to pretend to go back in time", it's "be direct with your children".
