The reasons for war are rarely absurd, and are about groups competing for limited resources. Saying it's anything to do with 'macho-ism' (which is certainly nothing like an ideology, if it is anything at all) is smug feminist nonsense.
Well, macho-ism is an abstraction constructed/used in order to communicate about some system of ideas or ideals related to "having pride in one masculinity". I am not interested in discussing whether or not this is a cause of war or not (but obviously it is a cause of conflict).
My previous comment was a parody of its parent (even if I tend to agree with what is said in it), the desired effect was to reveal how intensely absurd was the previously evoked " parent".
So you go: why are the reasons for wars so absurd?
Was machoism the cause of Gulf War 2, or the Ukraine war, to give two recent examples?
