Rewrite 

I think this article violates No personal essays (imho so does "Intelligent design"). In my opinion most of the stuff can and should be moved to Creation science, History of evolutionary thought, Evolution, Erasmus Darwin, and other places. 
The current "definition" of evolutionism on this page is the same as Evolution. I think a more correct definition and introduction would be something along the lines of
"Evolutionism refers to the belief in the scientific theory of evolution. For the most part, the term is used only by Creation scientists who believe the theory is unsound. Often the phrase is used as a perjorative to draw attention to what some Creationists believe is closed-mindedness amongst scientists...etc"
What do the regular editors think?
