I hovered over voting him down because it was such a terrible statement; but it certainly was not trollish. I think he honestly believes that a minefield is a legitimate answer. Whatever logical and moral failings he may personally have, we can still engage his argument on an intellectual level with reason and evidence.
I wholeheartedly agree with your sentiment. I'm not even sure how to approach such a misguided argument. So I haven't yet, because I didn't want to lower the level of conversation on hn.
I simply meant to encourage you to avoid snarky one-liners like one you've posted, and instead raise the level of discussion here.
