liberals who revert to ad hominem

Actually, the whole link of Hitler to Darwin is an ad hominem attack on the theory of evolution.

[Wallace T.]

Per Wikipedia: "An ad hominem argument, also known as argumentum ad hominem (Latin, literally "argument against the person") involves replying to an argument or assertion by attacking the person presenting the argument or assertion rather than the argument itself." Neither Hitler nor Darwin are presenting the arguments on this thread, thus any argument made against them cannot be considered ad hominem arguments. Granted, some creationists carry Darwin's theory of natural selection well beyond the meaning of the British scientist. They would be wiser to attack such derivatives of Darwinism as eugenics or scientific racism.
