"Naturally you can try to hold up some irrelevant extreme that no one else suggested. Any of us can look good against an extreme, but no one said that evolutionists thought they knew everything. I said in this specific field, evolutionists were ready to write off further study because they were inhibited by belief in evolution."
Emphasis mine
That is quite the leap. Are you saying that the belief we all have a common ancestor in some way contributed to the belief that genes were the only thing we should consider? How would that work?
