How tediously typical of fundamentalist Christians to quote Professor Dawkins out of context. Had Deputy Dog done a little bit of research he would have realised what a twisted, inaccurate poorly-realised nasty piece of misinformation it was. But why should he? The writer of the piece clearly didn't do any, missing as she did the entire point of what Dawkins wrote (as an afterword to a book, not a letter but she can't even get the basics right).
It's all too common for small-minded religious bigots to jump on someone for daring to ask questions that may have uncomfortable answers. Trying to hold on to their ancient scribblings, they seem to have no scruples about defaming people who don't kow-tow to their attempts to hold back the tide of advancing technology and morality.
Shame on you, Deputy Dog, for being too willing to believe such pap.
