What does Charles Johnson know about artistic expression?

CJ complains about a British film, which uses the fictitious assassination of Prez Bush as the starting point to explore strands of thinking in contemporary America:

This kind of thing used to be considered beyond the pale, way outside the realm of legitimate artistic expression. Now it’s "edgy:"....

Presumably as 'edgy' as photoshopping Palestinians women and children whose husbands and fathers have been disappeared by the Israeli army as holding up huge portraits of Elvis Presley or naff animal postcards (http://www.littlegreenfootballs.com/weblog/?entry=5712).

Or as 'edgy' as repeating the lie that a Lebanese civil defense worker whose job it is to rescue people is actually a Hezbollah propaganda stooge.(http://littlegreenfootballs.com/weblog/?entry=22260).

Or perhaps as edgy as lying about an incident so as to portray peace protesters as terror sympathizers.

The world has a lot to learn from Charles 'edgy' Johnson.
