You are so far off base it isn't funny here. The charge of anti-Semitism is made so often because of the incredible amount of anti-Semitism that still exists in this world. You may not see it or feel it in northern Kentucky. Indeed, there is very little anti-Semitism in America and it is not socially acceptable in the U.S. Generally most of the people who utter anti-Semitic comments publicly are from the lunatic fringe of the far left or far right. We see it at "peace" rallies where impressionable leftist young people have taken the Palestinian narrative and the Islamic agenda to heart with no knowledge of history or of what is truth and what is lies.
In the U.S. the fact that a major presidential candidate is Jewish is no big deal. Joseph Leiberman certainly didn't cost Al Gore votes in 2000. If anything his perceived integrity help offset Gore's incessant lies and half truths. It's easy to look arount the U.S. and your community and to have a hard time seeing a whole lot of anti-Semitism.
Much of Europe is very different. Large Muslim populations coupled with centuries of visceral anti-Semitism have lead to an explosive mix. Oh, it isn't all of Europe. Ireland has never persecuted it's Jewish population at all and has had Jewish mayors of Dublin and, I think, at least one Prime Minister. However, watching the re-emergence of popular anti-Semitism in Germany, Austria, France, Belgium, and to a somewhat lesser extent the U.K., is very frightening to those of us who are Jewish and still have family in Europe.
The charge of anti-Semitism should and does have a lot of currency still. It should with you as well, and any such charge, if justified, should bother you as much as any other form of bigotry. I also think being offensive is worse than being sophomoric.
