It's not an ideological talking point that people who die earlier due to health problems don't cost extra in pension funds. It's just a fact: if someone dies at 55, he won't cost a pension system which starts paying out at 65 a penny. fpgaminer posted much the same thing.
Nor, I think, was my aside about taxes being enforced with violence an ideological talking point: it's a fact that any law is ultimately enforced with violence. I honestly don't see how mentioning a social cost in the context of cost-benefit analyses could be considered a violation of any of the HN guidelines.
I'm not trying to derail or be argumentative; I'm honestly trying to understand how a fair moderator could threaten me with a ban for my comment.
Otherwise I feel that there's a loaded gun pointed at my head and any random statement is likely to set it off.
