The survey found that people who held anti-Jewish and anti-Muslim views tended to be older and less-educated than those who did not. Surveyors bundled France, Germany and Spain, the Western European countries where such views were most common, to draw a picture of those holding ethnic-based negative attitudes. They found that most anti-Semitic people were anti-Muslim as well.
People ages 50 and older express more negative views of both Jews and Muslims than do those younger than 50, the survey said. Similarly, Europeans who have not attended college are consistently more likely than those who have to hold unfavorable opinions of both groups. They also tend to support the political right in Europe, it said.
So, in Europe, the political right takes advantage of older voters (who likely fear change) and the uneducated or less educated.

Despite the increase in anti-Jewish sentiment in Europe, the deepest
resentment of Jews exists outside Europe, especially where Muslims predominate. Favorable opinions of Jews rank in the single digits in Turkey, Egypt,Jordan, Lebanon and Pakistan.
Not surprising because of state-run anti-Jewish propaganda campaigns by radical-Islamic regimes.
