Sure, but you can't accuse him of doing this unless he actually makes these arguments.
Doing so equates to the same fallacy that intelligent design adherents make, which is that since evolution yields ugly, selfish behavior, it must be wrong, or at least we should keep our mouths shut abou tit. Peterson is just pointing out how things are, not how we should design our policies.
I think he should probably be more responsible in qualifying his statements to prevent his simple minded followers from jumping to the wrong conclusions, but that's about as strong of an indictment as I think one could make against him, at least in this context.
