Thanks for this. I was watching it yesterday and thought 'there is no way everyone was ok with bicycles' when he said that. It is not human nature. I also think a healthy dose of skepticism is good as long as we fall back to scientific data.
I was surprised that comment went through a production of dozens of people and no one saw a problem with it.
Yeah, I was quite surprised by this historically incorrect analogy when I saw the film, but this does not invalidate many of the other good points that was made. Every argument should be evaluated on its own merit.
