The question of how to moderate politics on HN is a complex one because political stories are mixed: some are on-topic and some are off-topic. We can't exclude them all, but we can't include them all either. It depends on which stories contain significant new information and can support curious conversation. For more about this, see https://hn.algolia.com/?query=political%20overlap%20by:dang&.... Some good places to start are these threads:
I highlight this because one of the difficulty I often face as a user on foreign social media networks is that the foreign mods are unfamiliar with our country's history (political or otherwise).
And so I find they often resort to the easier way of just removing the posts that have the most complaints, without realising that this is also one of the strategies used by the online troll army to suppress genuine criticism (all the "flagging" that you see for such posts are often online brigading by the troll army abusing the reporting tools).
In other words, the controversy is manufactured for something that isn't really controversial, and the mods are forced to step in because of the controversy and remove many of the posts, which is actully one of their goals. You unknowingly help them.
(Unfortunately, I cannot also offer a practical solution to this).
