By killing God, evolutionists kill that which gave rise to our Western Culture, namely Christianity. By killing Western Culture...
To control the present is to control the past and, hence, the future of mankind.
booze and war are under no threat from evolutionary theory.
Second, while some of Western Culture can be attributed to Christianity, pre-Christian cultures have also informed what is now Western Culture: there is, of course, the influence of the Jews (who are not Christian); but you cannot discount the Romans (constitutional government, the rule of law), or the Greeks (mathematics, engineering, the concept of research, the roots of modern medicine [think Galen], military organization and drill). Indeed, one can accurately claim that Christianity actually stifled Western Civilization for centuries until the re-emergence of classical thought in the Rennaissance.
Ooooookay... You really need to stop reading the creationist propaganda and get out in the real world some more.
And it has apparently escaped your notice that the *majority* of Americans who are "evolutionists" are *Christians*. I'm sorry if that punctures your cherished preconceptions, or makes your head explode.
