The leadership is Jewish. You can argue America in the early 1900s during Jim Crow was not technically segregated and disenfranchised. Looking at facts without context is very misleading. The leadership themselves described their neighbors as animals. It is a nation based on dehumanization for the establishment of a religious ethnostate (hence the law of return aimed at Jews and not Muslim or Christian arabs for instance). Making any excuse on behalf of Israel is frankly mind-boggling. It is a tale of the slave feeding his master. Although many Americans stood for South African apartheid, so it comes as no surprise when fed propaganda, most of us will choose what to believe. Part of me wishes we exposed more of those Israeli farms etc, but it will come at a dear price if you do so (remember Congress is controlled by AIPAC, and they will throw the book at you if you do)
This serves to demonstrate that “Arabs” residing in Israel (with all the complexities of Israeli residency omitted for the sake of time) are relatively underrepresented in the Knesset.
You’ve shown less than 10% of the Knesset is “Arab” (for Israel’s peculiar definition of “Arab”), whereas 20+% of the population is.
