I would love to hear a full analysis from your part on the question of "are the reasons of war absurd" because I am not convinced by your argument about "groups competing for limited resources" and honestly it felt like a clumsy generalization of some facts (which could be made-up).

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".
