Following the murderous shooting rampage of a rabbi and three students at a Jewish school in France, a new study finds that anti-Semitism is widespread across Europe.

This means the idea of not liking someone based solely on the fact that they are Jewish is growing.

The Anti-Defamation League (ADL) conducted the research that shows 24% of French citizens held anti-Semitic views—up 20% from 2009. Meanwhile, four in 10 Europeans say that violence against Jews is the result of anti-Jewish feelings.

"Those increases are all the more disturbing in light of the shooting attack at the Jewish school in Toulouse," said Abraham H. Foxman, ADL national director about the shootings in France.

Approximately 500,000 Jews live in France, which is less than 1% of the population. However, it is the largest Jewish population in western Europe. In comparison, the U.S. has much more positive attitudes towards Jews.

The ADL found that 15% of Americans hold anti-Semitic views. Meanwhile, nearly one in five people believe that Jews have too much influence on Wall Street. Currently, about 2% (6.5 million) of the Jewish population lives in the U.S.
