Turmoil in China

We always say in St. Maarten that black people can't work together but seeing what is going on in China the past few days, I realized that not only do black people have issues with each other light skinned dark skinned etc but other races do to. The difference is that for economical reasons when these other 'races' are outside of their country of origin they put these differences aside and work together for their benefit. When will we learn that??
