Today I learned: even allegedly smart posters on HN can be unable to understand context.

There is an odd phenomenon prevalent on the 'net: the presumption that a short blurb written with a small audience and particular point in mind should, somehow, contain encyclopedic completeness to every conceivable objection any twit may conjure up, no matter how ill-informed or tenuously applicable.

That´s why sometimes silence is the only viable option, any other one only receives mental onanism as a response, the conversations ends in the same place but with the OP mentally exhausted.

Fighting wars? or just fighting? His context was about fighting wars, not just a couple guys running into each other and throwing a few punches.

There's always ambiguity there, unless you're so delusional as to think you knew exactly what they were thinking and meant, and the exact context.
