We have a somewhat similar reaction to eating brains for instance, yet that’s probably one of the safer part or the animals we eat.

I think a lot of the reactions we built over hundreds of generations need to be revised in the world we are in today, and in light of what we know now. One of the interesting one is our reaction to body sizes, and how we still have an instinctive reaction to tall people, when it makes no sense in most of the societies we live in.
