Throwing around terms like ‘creationists’ or ‘creationist sites’ is a cheap trick. I have never visited a ‘creationist site’, and I believed in Darwinism most of my adult life until I learned of the advances in microbiology and remembered my statistics.
The advances in microbiology and statistics have not disproved "Darwinism." Behe's ideas have been shown to be invalid by mainstream science. His latest book backs off from many of the ideas he put forth in the 1990s.
Check the reviews I linked to in a previous post.
