I would like to say this didn't surprise me, but it was still stunning to see someone admit to it:
"When I wrote my book, The Heresy of Ham, one of the things I noted was that, as strange as it may sound, arguing for a young earth (or a historical Adam, or an actual worldwide flood 4,000 years ago) is actually not the real concern for YECism. The real focus is that of “fighting the culture war.” Thus, a literal-historical reading of Genesis 1-11 is really just the weapon used to fight that larger culture war."
It makes a lot of sense, and is what I have suspected all along. Creationist sites have made this all too obvious, such as all of the personal and religious attacks on Darwin, Dawkins, and other evolution supporters. For example, this recent article over at Evolution News & Science Today tries to claim that Darwin and Dawkins have caused an increase in a belief in witchcraft. Why would an organization who professes to be non-religious and focused on science take it's time to to write and publish such articles?
