I wasn't trying to say that white Jews have lost their heritage, or even necessarily that they didn't have any ancestors from the middle east.
The truth is, biblical times were so long ago that we can't have any perfect idea of who inhabited it and what color they were, but it's really not important.
The fact is that before WW2 and Zionism there were Arabs on that land and if you go there today the Arabs have been pushed back and trapped into a comparatively small piece of land now called Palestine.
I'd also like to point out that you called the very idea of Jews getting their skin color from interbreeding a racist myth but you claimed that modern Arabs got their skin color from interbreeding.
The only thing I said that could be "patently incorrect" is that the Jews of biblical times aren't the ancestors of the white European Jews. The truth is that the Jews of biblical times are the ancestors of people from many different ethnic backgrounds.
