That said, did it even occur to you that suggesting a dispute between two grown adult men should best be solved with wrestling or a competitive round of video games is in itself infantilising?
This doesn't resolve the dispute, it just uses a feat of strength to establish literally unquestioned dominance (even if that dominance is purely situational and would require re-establishing on the next dispute).
Resolving a dispute involves, y'know, actually talking and understanding each other's point of view. But that requires empathy.
