Among the tin-foil hats there's frequently a gem - this guy is the real deal. He approaches these issues with a perspective that's not entirely based in Judeo-Christian ethics (not that that's bad) but also shows the practicality of alternatives for issues like stem-cell research (adult human and umbilical methods have shown AT LEAST as much promise as fetal) pain control and euthanasia.
He is well worth a listen and a read!
err, I thought that the tin-hats, aliens and bigfoot were the gems...
