My response: To answer this question concerning 'a Christian', it is clear that good, real, holy Christians have held all sorts of views on this subject. It often boils down to specific persons in specific contexts - and views on race will depend on that person's knowledge and experience.
But Christians should be, must be, honest. The main problem nowadays in relation to race is sheer dishonesty - from 'special pleading', unilateral emphasis, and denied assumptions; to the most extreme lying.
So, for some people in some situations, the range of legitimate views on race are limited by the Christian requirement for honesty.
