If I was told to sacrifice something to prove my devotion to God, if I was told to do what all monotheists are told to do and admire the man who said 'Yes I'll gut my kid to show my love of God.'
The noble title of "dissident" must be earned rather than claimed; it connotes sacrifice and risk rather than mere disagreement.
Our weapons are the ironic mind against the literal: the open mind against the credulous; the courageous pursuit of truth against the fearful and abject forces who would set limits to investigation (and who stupidly claim that we already have all the truth we need). Perhaps above all, we affirm life over the cults of death and human sacrifice and are afraid, not of inevitable death, but rather of a human life that is cramped and distorted by the pathetic need to offer mindless adulation, or the dismal belief that the laws of nature respond to wailings and incantations.
The pre-history of our species is hag-ridden with episodes of nightmarish ignorance and calamity, for which religion used to identify, not just the wrong explanation, but the wrong culprit. Human sacrifices were made preeminently in times of epidemics, useless prayers were uttered, bogus miracles attested to, and scapegoats - such as Jews or heretics or witches - hunted down and burned.
