Yep, typical behavior from the chinese. Everyone who grows up in that country seems to carry a grudge to empty out on someone whom they feel deserves it. You will not realize that a casual remark, harmless comment, or a simple smile towards someone can be interpreted as some flaw in your personality that needs to be exposed and punished. Of which case it serves you right in their minds. The disgusting ignorance carried by the populace which believes that cruelty is a virtue needs to be exposed for all to see.

Sometimes just because a country or culture has been around for a long time doesn't mean they've remembered what brought them there in the first place. You can certainly say most of the good stuff was definitely forgotten along the way!
