Here is my advice to you, since you seem mild-mannered! Try to meet some people of other races and religions. The beautiful things of where I grew up was that it was very integrated. I still have friends that are black, latino, Arab and Asia. I was the only Jew around, but I never felt any antisemitism. You will find that they have the same problems as you do. You will find that there are Blacks, Jews, Arabs and Latinos have their share of assholes, like the white race has, but then you will find that they have their share of great and intelligent people also! This country has survived because of its diversity not in spite of it!
Here is a little tidbit on the Jews: Most of the real religious Jews, the ones that look like the Amish usually make up the lower income level of the Jews. The ones that are the CEOs, work in the media and financial markets are usually less religious! Also to knock out a common misconception, American Jews by in large perfer America over Israel! Yes most of us support her, but if it came between Israel and America, we surely choose America. Just look at the last election, there was no doubt McCain would support Israel, there were and still are many question marks of how Obama will support Israel. Yet they went with who they thought was the best candidate (Not me I went with - Mitt Romney, yes I wrote his name in)!
