What you posted is factually correct. From observation, HN has turned into just another Slashdot, unfortunately. I came here to escape from Slashdot's obvious liberal-biased bubble, but the infestation has happened here too. No doubt this post will be downvoted into oblivion as well, including the other replie(s) I've made on this topic. :(
There have been plenty of non-flagged stories on both UK and US politics where they deviate from the regular, with discussions that haven't descended into flame war and a sea of greyed posts. Not specifically relating to tech, but are exceptional in some way. e.g. Brexit and the various constitutional shenanigans, some surprise USSC or agency ruling etc.
Reasonable discourse has resulted with good points on both sides - along with a minority of both sides playing it like reddit - black/white voting, and absurd easily disproved comments.
The "day-to-day" and regular politics can stay in the reddit cesspit.
