Is Hackernews just getting overrun by pro-Xi commentators that make up whatever they want now? Chinese air pollution is ridiculous, and it's primarily because of their massive amount of vehicle emissions: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6526014/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6526014/

That link points out that air pollution isn’t “primarily” due to vehicle emissions except in some cities. On both regional and national scales, vehicle emission has been identified as one of the most important contributors to air pollution in most cities in China (Gong et al., 2017; Wang et al., 2010; Wu et al., 2016), and has even surpassed other contamination sources in some cities.

"Lots of air pollution" and "lots of electric vehicles" can be true in the same sentence. Vehicles are not the only source of severe air pollution.

  * EVs are not a solution to air pollution, most air pollution from modern cars is from brakes and tyres. * OTOH, China is really ahead in battery-powered 2-wheelers, that replace the old scooter fleet, and that ought to do something. * Still, China's air pollution is for the main part due to massive use of coal power, incinerators, and desertification bringing sand from Gobi desert. The linked study from grand-parent doesn't even mention any of these.

HN's community is large and therefore divided on divisive topics. That's more than enough to explain why there's diversity of opinion on, for example, geopolitical topics. Everyone needs to abide by the rules in the presence of such topics so that this place does not end up burning itself to a crisp. Therefore, please don't post to HN like you did here—instead, please make your substantive points respectfully and thoughtfully. If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.
