Sorry but this is science, and science is judgemental. It is not possible to say that variation is really not required for selection but we still include it in the definition anyhow, because well, we like to suit the theory for evolution. Oh and then accuse of me of misrepresenting when I am just enforcing systemacy of knowledge, that is rich.
You also fail to mention my arguments why and how selection without variation provides meaningful knowledge. Since I explained this about a dozen times how this is meaningful, it is strange that you make no mention of it, and simply proceed to focus the theory on evolution again. What I mean to say is that you and others have been stubborn to a fault in not recognizing my argument, as you are here. I know what your argument is, and it isn't much.
I can't see how a change in the definition of a fundamental theory would be insignificant, that is a very weird idea you have there about fundamental theories being so maleable. You say variation is not required then there is no variation in the baisc definition of Natural Selection, and you are non-variationist Darwinists, end of discussion. There is no other possible conclusion by rules of science.
