Because there are ethnic "Jews" and religious "Jews". Religious Jews honor God's commandments (laws) and understand what it means in God's eyes to be one of God's chosen people and what their responsibilities are. Ethnic Jews are merely Jews because they are descendants. They do not know or care about God or Israel, they think of themselves as modern and progressive and free- thinking and moving away from the "old" ways. To me, it's very sad that they would give up that great heritage for the ways of the world.
That makes perfect sense. Thanks for the reply.
