Scepticism (or Skepticism to use the American spelling) in its pure sense of objective criticism of absurd paradigms is not necessary the same as materialism or reductionism. But too often Sceptism does degenerate into a form of reductionist Physicalism. For some reason such Sceptics (and they would make up the 99.9999% majority) are reluctant to turn their superb analytic tools on to their own paradigm. They debunk every other paradigm except their own
Still, Scepticism can be pretty useful for playing "Devils Advocate" to some of the more absurd religionist, new age, and para-scientific paradigms

The Skeptic Tank's WEB Pages
"The Skeptic Tank is a BBS which maintains extensive archives on destructive groups, individuals, and ideologies with special focus on religion's impact upon history as well as religion's impact upon rights, liberties, health, and safety of the world's populace in contemporary times. Newspaper articles and information about various groups and individuals and their destructive ideology-drive activities are provided upon request free of charge to serve the community.
The Skeptic Tank also maintains as a primary focus the scientific debunking of claims of the paranormal. This includes all testable claims of the paranormal from aliens in flying saucers to vague, ill-defined conspiracies. Untestable claims of the paranormal are really of no interest as metaphysical queries are pretty tiresome and pointless and there's enough testable claims being made by paranormalists that should be addressed. The activities individuals perform as the results of those beliefs, however, are subject to scientific inquiry as as such The Skeptic Tank considers such its venue. "
