Please don't post political, nationalistic, or ideological flamewar comments to HN. It's not what this site is for, regardless of which side people are battling for or how right they feel it is.
I get what you are saying, but this was a submission on political protests and the government's somewhat repressive measures against it - so it is hard to discuss it without politics .... perhaps this submission should have been removed in and not allowed to gain traction in the first place? Can I flag such such submissions that have a political undertone?
It's not a question of discussing it without politics, but discussing it without flamewar. That may not be easy, because people quickly get angry and attack each other, but it's definitely doable, and that's the bar that political discussions on HN need to clear.
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:
Just sharing my perspective here - I noticed that US political posts are actually better moderated here than other non-US ones.
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).
