There's no such a thing as open mindedness.
Each race has a different culture that is in some instances the complete opposite of other race and they live according to their cultures and customs.
That's why Races are separated in different geographical areas.
Blacks cannot live with Whites and browns cannot live with yellows, Christians cannot live with jews and muslims cannot live with Christians and vise versa. Everyone has a distinct cultural, mental and physical makeup attributed to their distinct genetic groups.
And forcing the so called open mindedness aka tolerance aka political correctness down people's throat is just the complete opposite of Nature.
The question you should ask is: Be or Not to Be!
