There are a high percentage of Israeli citizens who are Arabs. Israel was founded in a land where people spoke Arabic. It makes perfect sense to accommodate them.
I also don’t like the American nationalistic, xenophobic attitude of “this is America! Learn English you foreigner!” It’s one of the things that conservative goyim are mistaken about. It’s not a torah idea; we are told to love foreigners if they are keeping our beliefs and ideals, whether they are a ger toshav or especially if they’re a ger tzedek.
Asserting Jewish dominance just leads to Jews dying from terrorist attacks.
