Aren’t you painting with a pretty big brush when you say “bad design arguments are pretty bad”?
Bad design topics, including nested hierarchies, seem to be what I consider best practice:
Why would all primates except, Chimpanzees and Humans, who share the most recent of common ancestry, have functioning Vitamin C genes … while Chimpanzees and Humans have the same gene broken?
Is this a “bad” refutation?
