Some very good points there from Maren and The Mule.
The artist is responsible for his or her own intentions when creating a work of art, and in the case at hand, I find myself more swayed by the arguments against Leni R.
On a much smaller scale, remember that last Woodstock concert, where the riot broke out? Conditions were ripe for it when Limp Bizkit took the stage, and what do they do? Play a tune called "Let's Break Something" (or whatever the title was), basically inciting the riot. I found that to be very irresponsible, mainly because of the potential for injury or rape, not to mention all the damage to the site. Since then I have had no respect for those guys, especially the singer.
