That has been scientifically proven. It has also been proven that all members of all semitic religions think alike. Soon after they are born, these thoughts are inserted through special prayers kept a total secret by the priests of those religions. So they all think about nothing but power through sword throughout the day. The men think about it more frequently than they think about sex, and so their numbers grow at a lesser rate than non-semitic religions.
It has also been proven that no other religion believes in power through sword. All the reverse things happen to those. None of the members think alike. None of them think about power through sword at all, at any time of the day, not even when they are on the potty. They think about sex more than they think about power through sword, with the obvious consequences.
