Taryn Flynn gets one thing right in "Jesus Wasn’t White And Here’s Why That Matters." The Jesus figure is generally believed to have been a first century Middle-Eastern Jew. Such a first century Jew would not have looked like a modern Western European white guy. Virtually everything else in the piece is, of course, complete non-sense since it all relies on assumptions and willful ignorance. Not only is there no historical evidence for Jesus existence to begin with even if you could make a case for Jesus existence you then have the problem of deciding on which Jesus was the real one. The scriptures that contain information on the Jesus figure do not agree on any aspect of that figure. They actually seem to describe separate individuals. Or, more accurately, separate perceptions and preferences for a Messiah persona.
Though it is true that the Jesus figure would not have been a white guy it is equally true that the odds that he existed at all are very low. So it may not matter all that much. I understand why Flynn found the need to point out how this white version has been used for despicable purposes but it is not the only variation that has lead to negative consequences.
