I believe there are many Chinese people, visiting HN everyday to discover and share cool stuff, and look forward to conversations that are intellectually beneficial to the participants. If anything, I hope I'm one of these good people, not a troll.
When the situation started to get tight, the meaning of word "we" here is shifting to "we Americans", but you see, unless HN put up a rule to block Chinese users, they will be here. Still looking for fun stuff, but end up seeing the theme turning to "tension", "conflict".
They think differently. Some views may seem unfair, or don't make sense to them. They usually just keep quiet, hide the entries and move on. But sometimes it gets too annoying, so they'll also raise a few points.
It is you who thinks defending China is not ok. So in converse, there will be people who think it is.
It doesn't make one troll because she's not speaking in your favor. I thought this was all fine? Can we just, sit down and compute?
