The temptation is strong, when encountering views one dislikes, to regard the person expressing them as disingenuous and pushing some sinister agenda. This is why the site guidelines explicitly say "Please don't impute astroturfing or shillage. That degrades discussion and is usually mistaken. If you're worried, email us and we'll look at the data."

As geopolitics between China and the West heat up for reasons totally beyond this site, users here need to remember that HN is an international community where all are welcome. Being welcome, among other things, means not being slurred because of your national origin, language, race, and so on. It's nice that HN feels like a small and intimate place, but it's not a living room—when you post here, you're broadcasting to an audience of millions. Many come from very different backgrounds than you or I or any of us does, and they have just as much a right to be here as you and I and any of us does.

The image of "warding off Chinese commenters", which you invoked in your comment upthread, is dismaying and exactly what we don't want here. People need to listen to each other more, not less, when there is distance between them. I don't want to be part of any site that works against that.
