Definitions are important.
Generally, when discussing evolution, I am talking about the theory that all life that we see and interact with everyday originated from a common ancestor, and that random mutations and natural selection, brought to bear by environmental pressures, has the mechanistic power to build wholly new body forms and complicated biological systems and functions (legs from fins, for example). If we limit the definition of evolution to adaptation, changes within species, even random mutation and natural selection (such as microbe resistance to certain toxins), then we are all evolutionists.
Getting a meaningful definition of evolution from a darwinist is like trying to nail jello to a leviathan. You must be a creationist or IDer.
