Wheresmy has it down!!
Semitic is a linguistic category; a subfamily of Afroasiatic languages that includes Akkadian, Arabic, Aramaic, Ethiopic, Hebrew, and Phoenician.
The words, "anti-Semite", were used by Christian & Jewish Zionists to label people who were not totally in support of the Jews being given their own nation. It is a derogatory "LABEL" that can destroy a person's livelihood.
It has no basis in truth & it shines a bad light on the people who use it regularly.
In the NT, Jesus criticizes the hypocrisy of the corrupt religious leaders of the time. Why don't these people who love to label others with that -now meaningless phrase- "Anti-Semite", just call Jesus a "self-hating Jew"? Instead of calling those whom they now refer to as, "Anti-Semites", they can better show what they really want to say by screaming, "JEW HATER"!!!!!!
Then they can just look brainless & irrelevant, as they truly are.
.....I can see I was a little harsh there.....
What I really want to get across, is that when people feel the need to question, or even to the point of criticizing & condemning, actions that are being done, or have been done, by the leaders of Israel, or groups that tie themselves to Judaism, whether they're religious or not, using words that mostly show your hatred towards the people whom these words are directed against, does very little to guide people into your line of reasoning.
It doesn't matter who you are or what group of people you are a part of, when you, or your group, are abusing other people, you become the hooligan, the troublemaker, the villain.
