ghastly
That's a perfectly apt description of someone who desires the death of others, especially the death (by extension) of their own parents and grandparents in the name of some vague notion of "progress." And many of these same people then laud a vaccine that will increase the life expectancy and reduce the suffering of millions of people, oblivious to the contradiction.
In a way, this is a freeloader problem. The richness of the community here comes from people interacting and relating with each other over time. On HN people are welcome to do that anonymously (pseudonymously, for those who speak pedantic), but still need some identity for others to relate to. If you don't contribute that, you're freeloading in the sense that you're benefiting from what other people are giving, without giving anything comparable of yourself.
Dang, as far as I'm concerned, I'm the one who's contributed and asked for nothing in return. I never asked for points (karma), or the ability to censor (flag) others' posts I dislike, or the ability to de-emphasize those posts (downvote). Meanwhile, I routinely see "uberusers" here get leeway, not just from you, but from the flag- and downvote-happy users, that anonymous users like me do not get.
