In my experience, those that don't take any individual action rarely take any meaningful action on any other plane either. Either you get it and care, which means you do whatever little you can do yourself and work for changing the society, or you don't get it and you don't care.

Those that criticise individual action are most often the ones that can't bring themselves to sacrifice even the smallest pleasure or convenience, but still feel a small pang of guilt whenever they see other people doing their best to do their part.
