Anti-Zionism is not something I had even heard of until this last couple of years and I see it here on the DP as well. When I first heard the term it bothered me. It still bothers me. I am more of the everyone get along type. I wrote a post http://www.dailypaul.com/comment/2764794 about the holocaust and Zionism, but I still have a hard time keeping things sorted out and it still bothers me to see hatred towards Israel.
I believe the Semites are decendants of Shem. One of Noah's 3 sons who populated the earth after the World Wide Flood.
I believe Jew comes from Judaism which is a religion. I believe Hebrew to be the race of people who came from Jacob.
I believe Israel to be alot of things: A name for Jacob; a Nation; or a people devoted to God which could also include Gentile Christians.
I assume Zionism has to do with the creation of Israel in 1948 but I do not know that for a fact.
