Don't limit your argument to people! Genetic variation creates hierarchies in which some are worse and some are better. It is inherent to literal life. Arguing some arbitrary technology created sexism and power structures is a nonstarter.

You could argue that agriculture and modern globalization is exacerbating preexisting, inherent problems, but that's not the articles stance.

This is what happens when the "gender is a social construct" rubbish infects academia. They now start off with the assumption that men and women are completely equal in all ways and look for explanations for why that changed, agriculture in this case. Starting off by acknowledging biological differences (men being stronger and faster) and biological necessities for a group to survive (pregnant women make poor hunters and warriors) is now heresy.

You should quote the parts of the article that support your view that rubbish has infected academia.
