Continuing the discussion from Bilbo Defends' Behe's Irreducible Complexity:
It is true that we have to be selective in responding to critics.
For example, it would have been valid for me to ignore this criticism from an anonymous poster on the internet, who has missed my point entirely. It would be valid to be selective by ignoring it.
However, it is not valid to ignore critique from qualified scientists for over a decade, when making a scientific argument. It is not valid to ignore the strongest arguments against one’s position to engage only the weakest. And even then, there is sometimes benefit in engage really bad arguments against one’s point, as I am doing here.
