It's so interesting that you automatically became defensive about left vs right wing bias of this site.
The fact of the matter is that depending on the thread, it can swing in either direction. And that's the problem - you end up with unaccountable moderation via populism, which is the worst kind of moderation.
Hacker News is not a functional social space. It can't be, by design, because it has an easily-gamed and incredibly punishing form of user moderation. The incentives for abuse are abundant, and the potential downsides are negligible because the moderators who are supposed to be a check on these abuses are demonstrably hands-off.
> "Couching statements in soft language" is a significant part of keeping a polarizing discussion civil in my view, so that makes sense to me.
A Modest Proposal isn't civil - it's satire. It describes in flowery language how the poor could sell their children to the rich for use as food. The dehumanization is supposed to horrify and anger you, and the satire is contained in the limitations of pretenses of civility.
