From the HN Guidelines

>Be kind. Don't be snarky. Have curious conversation; don't cross-examine. Please don't fulminate. Please don't sneer, including at the rest of the community.

This type of tone only reduces the quality of HN. :(

To be fair, the original comment is also of low quality (and can be summed up as "People are stupid. Amazon good."), which is not what I expect to see on this website.
