Dear snowbunny3318,
First of all, your trailblazing desicion to attend Bais Yaakov, even as your family was non-religious, inspires me.
The bais Yaakovs, and any other Jewish religious schools do not dismiss, much less negate the countless stories in the Torah of equal opportunity. So numerous are the lessons of equality in Chumash alone, that they are always borrowed in Christain parochial schools to teach morals to their own students.
The Torah calls us “Mamleches Kohanim V’goy Kadosh” – a princly, holy nation above others, and the Gemara expounds on the word “Achicha”, “your brother”, refers to your brother in observance. So the Observing Jew is indeed singlar.
However, being that we are the Chosen People, we are chosen from on high, and not chosen by the world (In fact, history shows quite the opposite). It is a private singularity.
Doesn’t every religious peoples view themselves as singular?
That frum Jews are unnatural at embracing people from outside their creed, is an utmost virtue. It denotes of their sheltered childhood from the influences of gentile culture, and it certainly should not be compromised for ideals of cultural embracement.
I hope this helped.
