For someone who is obsessed with evolutionary psychology, insisting that humans are animals (and should behave as such), you seem to forget a fundamental fact: groups that fail to evolve stagnate and are outcompeted by groups that do. Evolution necessarily implies getting rid of certain traits and adopting new ones. In this case, keeping this Grug mentality is holding you back, and you get angry because subconsciously you realize you are getting left behind in the evolutionary arms race. <|endoftext|>
