Lately something I've seen a lot on Twitter, where I follow a lot of writers and other creative types, is the notion that "all art is political." Here is a detailed explanation of this belief from someone who popularized it and here is a rebuttal. I first heard of this notion many years before from a college acquaintance who's now a minister in a very conservative non-denominational church and an active Christian home-schooler (he said that all art has "a message" and essentially there's no neutrality), but it has gained especial prominence in recent years with the rise of various social justice movements online.
