Chinese are everywhere

So I've noticed that overseas Chinese turn out in overwhelming support of the country they fled so they could have a better life.  Regardless of issue, these Chinese talk like they're still Chinese nationals with little regard to where they actually live, in the US, Canada, Australia, Germany, etc

Cities like San Francisco are nearly at 30% Chinese population, how did this happen? 

I'm not against immigration, but seeing that they don't want to assimilate and protest against OUR policies on OUR soil, is it time to stop immigration from China?
 

Circumcision is harmful, perverted and disgusting.
