Interesting post. Esthetically, I dislike the orange but wear it even when not required because I generally hunt in dense cover and it's good to be able to spot one's companion easily and not worry where he is.

Then, of course are the slob hunters.

Indeed, orange is not worn generally in Europe but then the entire hunting culture is very different and I suspect that those who think that seat-belt laws and hunter orange laws are infringements upon personal freedom would not feel comfortable hunting in Europe.
