The restriction applies to everybody, not just Israeli Arabs. However it is true that Israeli Arabs are the ones most affected by it.

These days I live in the Southeastern US. Since 2020 was a census year, states have been redrawing their electoral maps. Several states have made changes that reduce the voting power of non-white voters. If politicians say this had nothing to do with race does that make it true? Even if it is true that they didn't consider race at all in the decision making process, does that make it acceptable when the end result impacts people in a noticeable way based on their race?
