Rush was talking about these protesters today. Apparently, on their website/facebook page/whatever they are discussing what they will be needing to continue to occupy.
They don't want to "buy" anything as that might defeat their anti-capitalist stance. Brilliantly, they are soliciting donations of goods and services (doctors, nurses) from people who have already made purchases and already supported the very capitalism the occupiers are attempting to bring down.
As long as it is not their money being spent, I guess it's okay for people to "give" them stuff. Convoluted, much?
