1859-1903 Herbert Spencer applied the doctrine of Darwinism to all areas of life, working as a tireless evangelist for the Evolutionistic religion. It's amazing how dedicated and religiously zealous evolutionists are to their cause. Spencer was an example of Darwinistic extremism, of which there are many examples today.  When asked why they are so dedicated, they reply that the idea of a Creator God is in conflict with their lack of morality.
