MgM, the idea that Zionism is a secular movement doesn't even take into account the meaning of the term, that borrowed from the Old Testament. In fact, the religious political parties dominate the policies of Israel and that the idea that the rabbis of Israel play no part in Israeli politics than does the house of bishops is blatantly incorrect.
That is analogous to the same propaganda that is given when we call the US a democracy today.

As far as the "dreary old bromide" to insist that the term Semitic be applied to only Jewish people is prejudicial and racist. The only accepted usage of the term being applied to Jews only is a propaganda device that has no relevance in today's Mid-East conflicts.

If you trust Wikipedia's entry, than I suggest that you take into account Tom Lehrer's
dictum: "Those who seek their knowledge through the internet deserve all the disinformation they get."
