You have no idea of the ground realities in the US especially with culture.You speak as though humans are some sort of primitive pack animals.
Culture and tolerance are the true binder, not language. We already see how 'united' blacks and whites in the US really are, even with a common language and religion.
Different people who see the big picture and keep their petty differences aside will be the real winners.
Not that you have the comprehension to read what I put regarding culture in my post.
As mentioned before, I do not consider your posts worthy of replying to so do me a favor of not quoting me.
