I don't have to. Dahmer is not an evolutionary biologist, has not studied the discipline, and to my knowledge has not kept up on the last few years of research.
Strangely enough, that's the newest quote you've yet offered. I guess that's a step forward, in some bizarre and twisted sense...
In actual fact, guys like Dahmer, Hitler, and Stalin were real evolutionists in that they actually lived their lives in accordance with evolutionist logic and precepts and according to the evolutionist notion that "survival of the fittest" is the only moral law in nature. The people you'd call evolutionists, in contrast, are basically just a bunch of yuppie nerds using evoluitionism as a kind of an ideological fashion statement.
