If you're going to comment about generational warfare, please don't propagate it while doing so. That just leads to more resentment and makes discussion less interesting.
When someone with the opposing identification runs into such a comment, inevitably they feel that their side has been excluded or treated unfairly. Then they feel compelled to respond in kind, leading to flamewar which we're trying to avoid here.
Also curious what led to this. HN seems to be very constructive and pretty boring to attract a Twitter-like action.
