By the same token, initial skepticism to recent claims of cold fusion, Hitler's diaries, and a 5th force have been well founded. We don't want to reject things out of hand like most scientists. We seek the elusive open mind. It's best to impartially examine claims. But, skeptics will jump in where there are direct paranormal claims.
Most skeptics are atheists or agnostics.
I take a bit of crap from both sides. But I think I can help both sides. Believers would be less open to the voice of an atheist. Some may get a sick joy from bursting peoples bubbles. In fact I know a number of people who have stopped subscribing to the main skeptical publication because they resented the surly condescending tone.
