It has been asked why non-christians post at "Atheist Central."

     That particular blog is, of course, a branch of Living Waters. I would suggest a couple reasons. One is a human tendency to warn against scams. Living Waters is a commercial enterprise (posing as a non-profit) which sells garbage in the name of "salvation." Another is that Living Waters deliberately misrepresents non-christians. I say that it is deliberate because the blog writer has been corrected numerous times, but he continues the same misrepresentations. Then there is the fact that Living Waters encourages people to try to get legislation passed which is hostile to non-christians. People are not threatened by some nebulous "god." But they are threated by an organization trying to pass its religion into law.
