Can you elaborate? Are you talking about national territorial disputes (i.e., war), or a dispute over where two domestic neighbors’ land boundaries lie? In any event, this feels like an attempt to win an argument by stretching it to cover something out of scope.
I wasn’t really attempting to win the argument. Just wanted to point out that while we believe we are above such things, given the right motivations humans will happily kill each other over a belief.
Unless that opinion is about who owns a specific piece of land.
