"There's another thing to consider. An artwork with a political message is first and foremost a work of art, and as such there's a place for it in the galleries. A political message in the forums is not a work of art in and of itself, nor is it discussing art. Frankly, I don't see a place for a politically oriented forum on Renderosity."

Well, consider that for some artists it's all about the political message. Art is not just about visual imagery.
