How is it that some people can rationalize their racist, bigotted views and reconcile them with being a Christian?

In the Middle Ages Antisemitism in Europe was religious. Though not part of Roman Catholic dogma, many Christians, including members of the clergy, have held the Jewish people collectively responsible for killing Jesus, a practice originated by Melito of Sardis. As stated in the Boston College Guide to Passion Plays, "Over the course of time, Christians began to accept … that the Jewish people as a whole were responsible for killing Jesus. According to this interpretation, both the Jews present at Jesus Christ's death and the Jewish people collectively and for all time, have committed the sin of deicide, or "god-killing". For 1900 years of Christian-Jewish history, the charge of deicide has led to hatred, violence against and murder of Jews in Europe and America."[3]

During the High Middle Ages in Europe there was full-scale persecution in many places, with blood libels, expulsions, forced conversions and massacres. An underlying source of prejudice against Jews in Europe was religious. Jews were frequently massacred and exiled from various European countries. The persecution hit its first peak during the Crusades. In the First Crusade (1096) flourishing communities on the Rhine and the Danube were utterly destroyed, a prime example being the Rhineland massacres. In the Second Crusade (1147) the Jews in France were subject to frequent massacres. The Jews were also subjected to attacks by the Shepherds' Crusades of 1251 and 1320. The Crusades were followed by expulsions, including in 1290, the banishing of all English Jews; in 1396, 100,000 Jews were expelled from France; and, in 1421 thousands were expelled from Austria. Many of the expelled Jews fled to Poland.[4]

As the Black Death epidemics devastated Europe in the mid-14th century, annihilating more than a half of the population, Jews were taken as scapegoats. Rumors spread that they caused the disease by deliberately poisoning wells. Hundreds of Jewish communities were destroyed by violence in the Black Death persecutions. Although Pope Clement VI tried to protect them by the July 6, 1348 papal bull and another 1348 bull, several months later, 900 Jews were burnt alive in Strasbourg, where the plague hadn't yet affected the city.[5]

In the Papal States, which existed until 1870, Jews were required to live only in specified neighborhoods called ghettos. Until the 1840s, they were required to regularly attend sermons urging their conversion to Christianity. Only Jews were taxed to support state boarding schools for Jewish converts to Christianity. It was illegal to convert from Christianity to Judaism. Sometimes Jews were baptized involuntarily, and, even when such baptisms were illegal, forced to practice the Christian religion. In many such cases the state separated them from their families, of which the Edgardo Mortara account is one of the most widely publicized instances of acrimony between Catholics and Jews in the Papal States in the second half of the 19th century.

Wikipedia is wrong here. Catholic dogma specifically condemned Jews for Deicide, as Christ killers. It wasn't against just the Jews at the time of Jesus but the whole race of Jews. The catholic church held this position long after the Jewish Holocaust and revised it's doctrine in 1965. Catholic dogma is evil. It's a disgusting religion.

hell yes. no one own more slaves than christians

Aphro iscwrong---Catholic doctrine has always insisted that tge Jews are not to be held collectively responsible for the death of Christ. The Catholic doctrine is that we all did, with our sins. We are all guilty of deicide. Which pope, council, or Church Father, Aphro, taught that the Jews are the only ones to be held responsible for Jesus' death?

Perhaps rather than the original question which leads us into speculation about historical 'evidence' often written for alternative purposes than simple factual documentation I would like to rewrite the question.

CAN a modern day 2016 follower of Christ (no matter what denomination they came from, and no matter the errors of their forefathers) justify racism?

Race was never a thing , until we made it a thing.

No.

How (after you change the question) do you define "follower of christ"?
I have noticed many christians denounce many other christians until it only includes a narrow definition that closely resembles the speaker's thoughts?
I choose to call anyone who thinks he/she is following gods wishes.
It's funny that christianity claims a majority in the u.s. but listening to the christians in this forum deny other christians it winds up to only having 27 people who are true christians.

Could different races be made by different Elohim(gods)?
Like different maker of shoes---
but shoes are shoes but different when made by different shoe makers?

Tell that to the guys who say so & so isn't a real christian because he/she is catholic or baptist or LDS or FLDS etc.

It happens all the time in here.

Jesus called non-Jews dogs because practically all non-Jews of His day worshipped a pantheon of gods instead of the one true God. It had nothing to do with race.

Racism is a result of original sin and is a sin of pride. Surely if Adam and Eve had not sinned, their children would not have the foolish prideful notion that people of one skin tone were superior to people of some other skin tone.
