I think it will be a fool's errand to attempt to explain this to some of the members here, but let's recall that 'race' is still based on 19th century classifications using phenotypical (appearance) clustering to classify peoples.
People with black skin and some other features were classified as Negroids.
People with yellow skin and other outward features were Mongoloid.
And people with fair skin and specific features were Caucasoid.
Due to the advances in genetics and biochemistry and other fields in molecular biology we know that these divisions are no longer satisfactory, though they may persist in typical discussions on race.
However, the fact is, for example, that it would be illogical to classify East Africans as Negroid (and not Caucasoid) since they are closer genetically to southern Europeans than they are to West Africans - and so on and so forth.
With this in mind, when members talk about race in this thread it is obviously a substitute word for 'ethnic group'.
Are European Jews genetically different from other Europeans to be classified as a separate genetic group? Since under a microscope European Jews are genetically different from other Europeans that they can be distinguished from other Europeans, it would hardly be inconsistent if some choose to classify European Jews separately from Europeans - just as East Africans were grouped apart from southern Europeans, though any substantial distinction between East Africans and Southern European is probably less than that between European Jews and Southern Europeans. After all, skin color is one of the quickest evolutionary adaptations according to scientists and may take only a few thousands years (perhaps less?) for a people to evolve lighter or darker skin if relocated to a region where the sun's intensity and their exposure is significantly different from where they once were.
The genetic differences between between European Jews and many Europeans - in-spite of centuries of cross breeding - are still great enough that one is able to distinguish between a European Jew and a so-called non-European Jew - and I say so-called because almost every European must have at least trace amounts of Jewish genes. And, needless to say, the opposite is more than true for European Jews. Despite this, the differences are significant enough to distinguish a Jew from a non-Jew.
For those who deny differences in intelligence, athleticism, etc between races ('ethnic groups') but accept genetic differences acquired by evolution for skin color, why would evolution stop at skin color only?
Are those (who have been mostly Muslim so far) who are adamant that all races are equal in each and every aspect people who simply deny evolution from the get-go? If so, at least their beliefs are consistent. But if you accept micro evolution, then why reject differences between races and ethnic groups out of hand?
