Just an observation, it seems HN is more interested in topics semi-related to China than BLM or policing reform. I wonder if this reflects something about HN readers.
I'd be cautious about drawing conclusions from what you happen to notice. People's general conceptions of HN are mostly drawn from things they saw that they disagreed with. There have been plenty of BLM-related threads also, and I'm sure there will be more.
HN tries to avoid topics that turn into flamewars. True, topics around China often turn into flamewars. But BLM and policing reform are even more likely to do so.
I think HN readers are smart enough to discern the relative difference in threat between redneck cops and a nuclear-armed, fascist state.
Also if you think tech isn't concered about "BLM" then you haven't visited a single tech website in the past two weeks. There are banners and calls for change everywhere...
