There are overtones of white xenophobia obvious throughout the short article, but I cannot plead innocent to these feelings either.
Xenophobia is a fear or prejudice toward strangers.
A rational person gets over the fear and mistrust once the cultural ice is broken and everyone realizes that we can live together in spite of religious or cultural differences. One point the author of that piece failed to mention was that Jews were more than coerced to become Hellenized. They were faced with a choice of conversion to the Grecian culture and pagan religion or death. I can't find any source to substantiate the claim that the Jewish elite encouraged assimilation into the Greek world. Yes, Judah Maccabee existed.
