In terms of actually impacting things worth a damn, it is on par with watching the West Wing and thinking that will somehow bring change.
When I think of the resources these people are flushing down the toilet to feel good when they could be spending money on being effective, I could freakin' weep. If the movement for black civil rights had wasted their resources on this "feel good and morally superior about ourselves" crap instead of training Rosa Parks to stand up to racists at Rockwood, black people would still be using unisex restrooms marked "colored."
