Funny how (possibly worse) anti-democratic massacres done by US allies (and much more recently) don't get continuous coverage US/Western/Business/Tech press.
Compare that how Tiananmen Square massacre is taught in China.
I assume the outsized focus on it is somewhat related to the lack of contrition and accountability.
School taught you the wrong lesson about it. ~Half the country (guess which half) supported it... And I've no doubt that they'd do so again.
