Yeah, gotta second DF there. Art should reflect all aspects of humanity from the very lightest to the very darkest shades, and all the levels and complexity in between... personally the reds in a splatted brain, (and even a gratuitously splatted one sometimes !) are still somewhat artistically justified in my book because of the reaction they provoke in us - after all is that not what art is aiming to do; provoke a reaction ? And not all reactions have to be nice... and arguably, perhaps we learn and grow the most from the ones that aren't ! I think if there is any place in the world where extremes should be permissible, or rather untrammelled, art is it.
