I foresee one end game for the far right. They know that power waxes and wanes. They know, certainly, that when they lose power their opponents will inherit this overreaching authority. The end game is to disenfranchise non Jews (Arabs), block them from voting, and keep Israel a Jewish apartheid state.
I know I sound like a rambling nutter but it's how I feel. I don't see and other rational reason to pass this law.
