I get it just fine. It is equally impossible to win a scientific argument
by using a definition for a term that has not been used by scientists for
decades, and then attacking this straw man.

I am NOT redefining evolution, I am instructing the non-biologists here
what the accepted biological definition has been for much of this century.
This seems entirely fair and appropriate to me. If anyone here needs to be
more explicit, it is the critics who deny evolution occurs, as to what
THEY think evolution is. I strongly suspect there is no consensus among
these people, while there IS a consensus among biologists.
