If we turn to the racial theory of the Third Reich , we will see that Armenians in no way belong to any of the Caucasian sub-races . They belong to the "Middle Asian race" or in another way to those people who are called Arabs, Semites and other inhabitants of the Middle East .
Even if the Armenian who wrote this looks like a Mediterranid (which in itself is VERY unlikely), he simply has no chance that being born into the Armenian people he will have 100 % Caucasian blood . Even if the impurity is not immediately visible, it will manifest itself in proportion to the aging process . The absence of impurities of non-Caucasian races is the main principle by which offspring between different phenotypes of the Caucasian race are allowed .
Anthropology with the typing of people is very subtle , and most of the people above, who wrote about the "similarity" of Armenians and Caucasoid phenotypes with dark pegmentation, made judgments on incredibly superficial signs, which leads to diminishing accuracies and errors .
Summarizing for the OP . The racial core of Armenians consists of Armenoids and sub-Armenoids. If you look like them, you are definitely Armenian and you should look for a wife among these phenotypes. If you look different, then you still don't belong to the sub-Caucasian races and you can't marry any Italian woman .
