Hi Salty,
As Mammuthus has pointed out, the word "evolution" has more than one meaning, and so you're just playing semantic games. It was pretty clear from context that people were not using your definition of evolution. I, for one, will not be typing "biological evolution" or "theory of evolution" very often, but will either write "evolution" or "TOE".
Depending upon context, Darwinism can be a synonym for the modern theory of evolution, or it can refer to the theory of evolution as it existed before the modern synthesis, or it can be a loaded term as Mammuthus mentions. Because of its vagueness I rarely introduce the term myself.
