Elmo, absolutely no one said that Ashkenazim aren’t from the MidEast. All Jews are originally from Eretz Yisroel, of course. That has nothing to do with the points made and no one said otherwise.
What was said, accurately, is that Jews from 3,500 years ago and Jews from 2,000 years ago were not darker skinned. No evidence has been offered, other then personal supposition based on nothing, that you could tell the difference between Jews in Eretz Yisroel 3,500 or 2,000 years ago from Jews today who came from Germany, Syria, Iran, Poland, Spain, Portugal, Russia or France.
