Living under a rock, I don’t know much about art, but I recently stumbled upon the work of Cleon Peterson: http://cleonpeterson.com/. I do not know what his political philosophy is, but his artwork primarily depicts whites being raped (http://www.thegatewaypundit.com/2017/05/iraqi-immigrant-arrested-raping-nursery-school-child-sweden/), tortured and dismembered by blacks and other races: just follow Google images and make up your own mind. But, I wonder if he had depicted white figures killing black ones, would his work still excite the establishment? It could have an impact regardless of the artist’s intentions.
For what it is worth, this artist’s art is even on the sail of a de Rothschild boat: http://www.mysailing.com.au/latest/edmond-de-rothschild-unveils-new-maxi.
