Hi, in this case, the title is referencing a quote and internet meme and is just referring to men. However it's quite problematic here IMO as it presents a cyclical view of history and masculinity that is both simplistic and incorrect.

Firstly, it promotes toxic masculinity by implying that men are either "weak" or "strong," with the former being undesirable. This feeds into harmful stereotypes that equate strength with aggression, dominance, and lack of emotional expression while devaluing attributes like empathy, emotional intelligence, and vulnerability. It also suggests that war and conflict is a necessary component for the development of "acceptable" masculinity. This dichotomy of "weak" and "strong" men reinforces an outdated and harmful ideal of masculinity and promotes a culture that shames men, among other things, for expressing emotions.

Maybe 1000 years ago, when "man" really just meant person and there was a different word for males in particular. Nowadays, to refer to people as "man" it just sounds archaic and vaguely patriarchal, but people do it anyway because sounding slightly archaic can give your words more power.
