Well I guess the fundamental disagreement is that I don't think these biases are best classified as illogical. Yes, if you are being completely objective, two job applicants should be judged solely on the basis of their qualifications. Yet, the one who is more polished is going to get the job ten times out of ten. Perception is simply a fundamental part of decision making, and I think the naivety lies in thinking that any of us are above catering to that perception or that we can somehow convince people to not rely on their perceptions.
