I see what your trying to say
All Jews are Semites, but not all Semites are Jews.
What is an "ethnic" Jew? A Jew born with 50% "pure" blooded background? Take a Semitic woman, history of family always Semitic, lets assume
Marries and has kids with a German immigrant who we would normally assume is 100% Germanic, but lets assume he has black hair and was the long
forgotten product of a Roman conquest and an misfortunent great great great great ect, ect grandmother.
Some kids look like Mom, we assume they are Semitic, some look like Dad, we still assume they are Semitic because they will carry on a few facial,
hair features, ect that could be used to distinguish someone as a certain ethnicity.
They are all Jewish, but they go one day to trace back DNA and find that their DNA splits off, maybe a short 100 years ago someone had a kid with an
Arab, or a Greek or a Italian.
Because they are the same RACE they will not differ different then a Semitic would, certain features passed down and so forth can put them in that
category, the only difference is that the ethnicities intermarried and now the "semitic" population is infected with a new DNA... which heaven knows
is a good thing because inbreeding of populations is what leads to off the wall evolution like say Germans have blond hair and blue eyes.
course isolated populations or even open populations choosing to mate with only those of their kind will always and have always existed, so maybe you
can still say the kids are Semitic, because they look so, and you can call them Ethnic, but their 50% German.
What I am trying to say is that no not all Jews native to ME are Semitic. All have a part of Semitic ethnicity in them, many have near pure blood
Semitic traits and some look like it but their blood diluted.
Of course, I am just nit picking because I feel like it.
Final point not all Jews (even Ethnic) are pure Semitic. Or even half. Why even
call them Ethnic Jews. Many probably claim to be, but are not. But of course, for generalization purposes we still call them all semitic, even the
ones that have absolutely no Semitic blood in them.
Isn't anthropology fun?
