The discussion of the evolution of human mating rituals is inherently political; it affects birthrates. It affects women's rights, which subsequently affect everything else, considering women are responsible not only for consuming most non-essential products on the market, but for being the sole demographic that is allowed to be intuitively eugenicists, discriminate in liberal societies, and have been allowed to do so since the birth of humanity. Especially when it's being done towards males.

"incel" posts are a symptom of said discrimination.
