Perhaps get a petition together of the other parents with real reasons why not to ban it. Put forth motions at the city council (or town meetings depending on where you live) and perhaps give examples and stuff.

And I don't blame right or left on this. When it comes to local politics, that stuff doesn't usually have any factor in it.

Heck, a cousin of mine has a side business filming all those sorts of local games and shows and selling copies to the parents. They buy it up and love it so what's the problem, really?
