In the wake of the Paris terrorist attacks which killed 130 people, anti-Islamic sentiment has increased all over the world, especially in Germany where far-right protesters demanded the closure of all mosques.
But here comes some reality-check directly from the FBI:
Terrorist Attacks on U.S. Soil by Group, From 1980 to 2005, According to FBI Database
According to this data, there were more Jewish acts of terrorism within the United States than Islamic (7% vs 6%). These radical Jews committed acts of terrorism in the name of their religion. These were not terrorists who happened to be Jews; rather, they were extremist Jews who committed acts of terrorism based on their religious passions, just like Al-Qaeda and company.
(The chart is misleading in several ways. For example, it labels “Extreme Left Wing Groups” and “Communists”, but not “Extreme Right Wing Groups” or “Fascists”. It should have either discarded all partisan labels, or included labels for both ends of the spectrum. In addition, “Latinos” is misleading, as Loonwatch is actually referring to Puerto Rican separatist groups, Cuban exile groups and the like. However, as shown below, many of the basic concepts are correct.)
