If every Chinese topic turns into the same "China vs. the rest of the world" discussion—or to put it more generally, if every thread gets sucked into whatever generic black hole happens to be nearby—then it becomes impossible to discuss anything specific on HN. Specifics are where the intellectually interesting material lies.
Compare the topic of the OP—electronics markets in Shenzhen—to what we see in this subthread: "China is waging economic warfare", "They aren't all evil", "Some are very evil", "HN is full of anti-Chinese comments and this will only continue as the war with Eastasia is in progress", etc. The generic discussions are always the same, and usually turn nasty, perhaps because the mind craves extra action or amusement to compensate for it all being so repetitive.

Particularly please don't create new accounts to take HN threads on generic flamewar tangents.
