I think this is a useful analogy, because it serves as a possible explanation as to why there seems to be a 'generation gap' whereby previous generations believe to a certain degree it is possible (and right, even) to separate the artist from the art itself, and why modern progressives are rejecting that (Although this gap is cleaner seen from a political perspective, I believe that to some degree it is also generational).
Previously, culture was seen from mostly a consumptive perspective. The bad people and their actions are 'on the other side of the glass' -- so to speak. Not only do the 'bad actions/opinions' not directly affect them, but they lack any true meaningful ability to change things. Strongly worded letters can really only achieve so much, and all of the information channels are centralized.
I don't know if this makes much sense, it's 3am...
