Article questions...

Whats the difference between simply raising a critical consciousness and having physically respond. I mean besides the obvious, ones mental, ones an actual action. If the goal is reveal social relationships/new social realities, wouldn't thought be just as powerful to one man, than action is to the other? 

(I feel like people's responses are much to subjective to say that art that actually makes people participate is any more effective...)

What does bishop mean that art created as a group has the "aesthetic benefit of greater risk"

Risk to affect people? Risk of actually creating change? Risk of getting attacked? Risk of being blamed for actions? Risk of...?
