Do you feel the same way about Israel? They are Jewish Nationalists. Are they not treating non-Jews as “second class citizens”? It’s a nation defined by its religion first and foremost.
Most Middle Eastern countries are “Islamic countries”, whose laws are dictated by the Quran and Sharia Law. Are Islamists “scary” as well? They treat non-Muslims as second class citizens. Are these people good or bad?
Black Nationalism, Christian Nationalism, White Nationalism, Zionism, German Nationalism all stink.
You don't know any Muslims and you've never lived in any Arab country .
