Any time someone tells you that men or women should behave a certain way because -~~*NATURE*~~-
Also whenever people pick out examples from “nature” to show how current human gender roles/stereotypes in our society are “natural”, they conveniently ignore animals like Penguins where the males take care of the eggs as a group where the females go into the sea to hunt food and replenish their body fat and energy stores that were depleted because of the strain of pregnancy. Then afterwards they take turns take care of the chick and going out to hunt. Nobody points to that as a way society could work (paternity leave in order to help take the burden of child rearing off the mother who has to recover, allowing couples to split time from work and staying home), even though that’s “natural” too. Nope, “nature” only counts as “natural” and the “way things are” when it’s an example that supports the current status quo and stereotypes that enforce that status quo. And we can’t learn anything from the way other species handle things either.
