Are not Jews way more fundamentalist than Muslims these days ?

They have about the same number. Islam came to being after Ishmael & his mother Haggar were kicked out of Abraham's camp by Sarah who was jealous even though she was the one who starting the wheels in motion by not trusting in God And telling her husband to lie with her maid in the first place. We (Christians, Jews , and Muslims can all trace our religious ancestry back to Abraham.
