Debating the concept of race does not mean that I in any way regard this as a quarrel between neighbors over where they come from. I have perhaps said enough when I said the alternative to assimilation is that immigrant groups form their own state or go away for lack of acceptance. Why should it be less serious if quarrels and dissensions are socially related? After all, the quarrels and dissensions between Russia and America are also not racial. And yet they seem to me extremely dangerous.
