@Setanta,
Setanta, I agree. As a "Buddhist"--at least as a follower of its philosophical principles--I am embarrassed by the historical indifference some sects have shown to the physical suffering of others, focusing ONLY on the psychic "dukkha" resulting from spiritual delusion. I should be even more outraged than you are on the grounds of your atheism. As a Buddhist I am also an atheist, but it's my--at least partial--identification with Buddhism, not my atheism, that should stir my outrage. You might include in your impressive store of knowledge the compassionate actions of many contemporary American and European zen Buddhists to the physical suffering of others. The names of masters such as Bernie Glassman and Thich Nhat Hanh come to mind when I think of zen activism.
I do sit around meditating, but I also do what I can--not as much as I can--to ease the suffering of the poor and oppose the arrogance of the powerful, but not while sitting on the cushion. Meditation is useful but not for everything.
