Hemant Mehta (the “Friendly Atheist”) is to be commended for pointing this out on an issue that has been extremely corrosive and inflammatory on atheist websites; so corrosive that many, myself included, chose not to write about it at all. I’ve deliberately refrained from accusing others of criminal acts, harassment, and the like on this site, for I feel that serious accusations like these are properly adjudicated by the authorities—usually courts of law—rather than by the commentariat of blogs, who, inflamed by rhetoric, often bay for blood.
But there comes a time, and the time is now, when those who traffic in such accusations must be called to account, particularly when they’ve erred, tarred someone’s reputation, and then, when their accusations prove to be false, quietly ignore them rather than admit error. This behavior is shameful and reprehensible, and Hemant properly calls it out. Go read his piece.
