Is anti-semitism still in use today?

Answer 1

YES. The Anti-Defamation League estimates that roughly 1 billion people, primarily in the Islamic World, but also in other regions, harbor Anti-Semitic attitudes. The European Union has noted that in since 2008, Anti-Semitism is rising in Europe, both from Muslim immigrants and from the European general population (although much more from the former). In the US, the trend was towards a decrease in the number of Anti-Semitic events until there was a spike in 2014. Additionally, Jews have consistently been over 55% of people targeted for hate crimes according to the FBI database where the victim was attacked on account of religion. When the overall numbers of the Jewish population in the US are taken into account, this means that a Jew in the US is nearly twice as likely to be the victim of a hate crime in the US than a Muslim and over 10x more likely to be a victim of a hate crime than an African-American. (African-Americans are more often victims of other crimes that are not race motivated.)
