No, Scanlon does not understand, as his sarcastic response
However we all know that LeFever understands. After all, he is a
world expert, as he has been so clear to tell us himself.
Personally, I always had a low opinion of people who feel that they
can win arguments merely by declaring credentials.

Neither of those works. They naive oversimplifications. I suggest
"Lifelines: Biology Beyond Determinism" by Steven Rose for a more
realistic view of the relation between DNA and organism.

LeFever can't read. I have not used the term "strawmen" to refer to
actual persons. My criticism has been of the extreme version of
genetic determinism that Scanlon has been preaching, not of people
doing genuine research.
