Hmmm... i see what your saying though that comment of his reads more like an artist enjoying their art affecting the viewer as intended, visceral and deep cutting far more than 'hahaha loser, i am so happy to have fucked with you'. What self involved artist doesn't want their work to have as strong an impact as possible on the minds of their viewers?
If we disagree beyond this i am just gonna drop it though, i feel like i'm sucking his dick even though i'm just trying to point out he's probably your typical artist and glad to be having such an impact rather than finding it funny.
