I think that I would also like to add that if such pedantic and pseudo-political art wants to fulfill any type mission even in the conceptual realm, then perhaps the creators need to find other professions. It has become clear that to follow any Marxist or even post-Marxist notion of emancipation in art is futile and that the artists are better off working for community centres and aid groups in order to have any real impact on the political and cultural fabric of society.
Artists are better at other things.
