Several of my friends have spent years working in China and they all comment about how almost no one believes in individualism in the same way that the average American does; that they don't care about civil rights or liberties (or give lip service to such ideals). That really does sound "different than us" to me.
Probably not. Why would it be 100% cultural and 0% biological? Because it makes you uncomfortable to admit any other possibility? I'm sorry, but reality doesn't care about your comfort level. It could be 100% cultural and 0% biological, or 90/10, or 50/50, or 20/80. I don't believe that the 100/0 scenario is very likely, because--despite your baseless assertion to the contrary--there are in fact real biological differences between East Asians and Europeans (or East Asians and South Asians, or any other racial group).
This is just a rephrasing of the original baseless assertion. The relative contribution of genetic and cultural factors to group differences is not at all clear.
I simply pointed out that this is not clear at all.

Watch the video of this riot ( http://v.youku.com/v_show/id_XNDUzOTYzMzQ0.html ) and tell me that it isn't clear signs of mob mentality. The pictures of the damage look bad but when you see the video it looks like a social gathering with people laughing (e.g. ~0:35) and nothing really going on, other than a handful of hooligans causing damage.
Here's a bunch of mostly white Canadians having a riot http://www.youtube.com/watch?v=4VzOUKODdZ4
