A short description of woo...

Beliefs that clearly demonstrate magical thinking, uncritical acceptance of things for which no good evidence exists. This includes, but is not limited to, psychic phenomena, ghosts, the paranormal, "energy healing," the use of "colon cleansing" and "liver cleansing" to rid oneself of "toxins," homeopathy (especially quantum homeopathy), and a wide variety of other mystical and pseudoscientific beliefs.

Woo is resistant to reason. Indeed, woo has a double standard when it comes to what it considers to be good evidence. It is very accepting of a wide variety of fuzzy, mystical ideas, but is often incredibly distrustful and skeptical of anything having to do with "conventional" science or "conventional" medicine. Woos tend to be very quick to react to defend their particular brand of woo and very unforgiving of its being questioned.
