But wait. I know there are racist/xenophobic Jews, in fact, I've personally met some

Of course, there are. Jews, like any other people, are prone to the same ills that afflict all of mankind. Judaism fundamentally rejects idol worship, yet Jewish history is replete with Jews relapsing into idol worship and other, far more immoral behaviors.

A brief read through the books of the Judges or Prophets in the Tanakh (Hebrew Bible) reveals this. Likewise, many modern Jews (particularly those who were forced to sojourn in Europe and the Americas) struggle with the effects of colonialism, racism, and other social ills that pervade our societies. As with most colonized, displaced nations, the people of Israel have internalized much of the same prejudices that persecuted them and their ancestors. Perhaps a great illustrative example is the great medieval Sephardic Rabbi, Yitzchak Abarbanel. Steeped in the Hebrew spiritual tradition, Abarbanel was a renowned commentator of the Tanakh.

However, his greatness in the world of Torah did not preclude him from the influences of his day and age; positive and negative. And having grown up in the country (Spain) that invented the concept of biological racism (Limpieza de Sangre), Abarbanel internalized these notions. In his writings, Abarbanel referred to the general dark complexion of Jews (himself included) as reflecting the curse of exile.

That the Gentiles (in his context the Spaniards) were pale because they experienced their joy at the expense of the Jews, and the Jews are swarthy because their blessing awaited their national redemption. This notion, and ones similar to it, was produced via the anachronistic imposition of contemporary Arab and European ideas of skin complexion and race on Judaism.

So while individual Jews have certainly introduced racist and xenophobic notions into Jewish thought, the power of Talmud Torah (the founding texts of Judaism and its study) is that it’s concepts and system has the ability to correct its own limitations.
