There are racists who use the term 'Christian' to describe themselves but that doesnt make them actual Christians. Actual Christians know the Bible better than that and know neither God nor Christ hate anyone or love any race more than another.
Regardless of the host of No True Scotsman fallacies and rationalizations you've been given, there are indeed racist Christians. Racists exist among every religion and every philosophy on Earth.
Christians who are racist have the same M.O. As any other racist- they use their beliefs to justify their intolerance. There are many passages in the bible that support intolerance for other races, tribes, and religions.
There is only one race?the human race. Caucasians, Africans, Asians, Indians, Arabs, and Jews are not different races. Rather, they are different ethnicities of the human race. All human beings have the same physical characteristics (with minor variations, of course). More importantly, all human beings are created in the image and likeness of God (Genesis 1:26-27).
To everyone saying "If you're a racist Christian, you're not a Christian." Yes, you are.( I'm not racist. Also not judgmental) don't judge others because they sin differently than you. All sins are equal in the eyes of God. But, I think that "racist Christians" believe that since God was not African American, Chinese, etc., then those races are "ungodly".
Jesus Christ is not racist and neither is God his father. In the Bible at Acts 10:34,35 it says "For a certainty I perceive that God is not partial, but in every nation the man that fears him and works righteousness is acceptable to him." It doesn't matter what color a person is, if they exercise faith in God and in his son Jesus Christ as well as take in knowledge of them both (John 17:3) then that person will be acceptable to Jehovah God (Psalms 83:18).
