I never stated of course that my religion is anymore justified than any other. I believe each individual has the right to practice their faith or lack of faith as they see fit. I have no authority to criticize their beliefs, as I am standing as blind as they. I can present my own view, for them to accept or reject, but anything else would be foolish. The only exception is when the practice of belief interferes with the basic rights that ensure we are all free to live our own conscience, as human sacrifice clearly does.
In any case, what you are describing is certainly not skeptical examination. It is mindless scapegoating. Human sacrifice in Africa has nothing to do with Shintoism in Japan or Mormonism in Utah. Mengele has nothing to do with Watson and Crick, or Einstein. Yes, religion, like science, like politics, like philosophy, like anything else can be perverted. But to use that as a bludgeon against all such thought serves only to drive one's personal agenda against religion, and does not represent any fundamental truth.
