I would like to think that some of those who deny the reality of race are still Christian, but to square such beliefs with the clear words of Scripture is no small task — if it is even a possible one.
God calls those who do not provide for their relatives (and those who deny race cannot even identify who their relatives are) worse than an unbeliever — they are literally apostates who have denied the faith.
Those who lack the most natural of affections (essentially storge) cannot even conceivably love anything else — their consciences are seared and their hearts are lifeless stone.
It does not seem that even felicitous inconsistency could save such men.
