But.. Europeans did put Africans into zoos and freak shows and display them, and European culture did consider them subhuman. Just study the history of Sarah Baartman, for an example. Mentioning that is neither dehumanizing nor defacing European culture, it's a statement of literal historical and cultural fact.

That said, I don't really buy into the theory being presented here. I would need to see some documentary evidence supporting it first, such as a common cultural association at the time of "broad noses" with "Africans" or an attempt to portray ancient Egypt as a Caucasian society. People knew where Egypt was. The pyramids, temples and other signs of civilization were still there. Knocking the noses off of the statues wouldn't hide anything.
