Apparently breastfeeding has offended people at least since 1741.
The book “Niels Klim’s Underground Travels” is a sci-fi/fantasy novel from 1741 by Ludvig Holberg about a man who falls though a hole into a world within our planet. He lands in what the author imagined an utopian society to be like, inhabited by creatures that resemble trees.
Even though the people there believe in a god, there is no real religion because nobody can know god’s will, and anyone can work as anything they desire as long as they are good at it, no matter ethnicity or gender.
Niels is deeply offended by this, especially when he sees that one of the country’s highest positions is taken by a “female palm tree” and he suggest to the king that women should lose all rights like in his world. What’s really offensive to Niels is that the woman breastfeeds her child! On the job!
This suggestion gets Niels kicked out of the country because it would weaken the country to deny half the population the right to work when there are plenty of talented and skilled women who might be better suited for a job than a man, and what the fuck is up with being offended by breastfeeding? Women’s breasts were made for feeding babies! Out!
Niels at one point end up in a province where men are treated like women. They have few rights and have to suffer constant sexual harassment in one form or another, and Niels can not believe how anyone can treat another person like that!
Niels eventually become the king of another country of dark skinned people and totally ruins their society, so you know, Ludvig Holberg was not fucking around and had no time for colonialism either. You can find the story for free on the internet.
