In my opinion, some people, such as Muslims, have the mistaken belief that if they just kill all the Jews, then God will make them the new "chosen ones." I guess they think that being "chosen" will be a blessing. Who knows.
It is no coincidence Islamic pagans hate Israel, Jews, Christians and Western Civilization. The entire basis of Western Civilization is Mosaic Law, something both the Neo-Pagan Left and the pagan Islamic thugs cannot abide and wish to destroy.
The very idea that human beings have individual rights not subject to the whims of an earthly monarch, but subject to the laws of Yahweh, is directly from Moses.
Historically, this is proven over and over again with the successive conflicts between the forces of paganism and the Judaic culture. (This includes the idolatry of cultural Marxist paganism.)
I read that book many years ago. All I remember of it is that Wylie hated Jews, but he hated Christians even more.
