So Muslims in Europe are more likely to be anti-Semites than non-Muslims in Europe, but there are more non-Muslim anti-Semites in Europe than Muslim anti-Semites because there are way more non-Muslims in Europe than Muslims. As a result, European anti-Semites are more likely to be  non-Muslim than Muslim. That's hardly news or statistically interesting. 
What would have been interesting are statistics about European anti-Semitism  in the post-war period from the 1950s to the 1970s in comparison to 1990s-2005 and to today. Anti-Semitism was rampant in Europe in the 1940s, and not just in  Germany, and it didn't suddenly disappear when the Allies conquered Germany in 1945. As for Canada,  I have occasionally heard vaguely anti-Semitic remarks from very elderly in-laws---I'm no spring chicken myself--and at first attributed this to their distant East European origins. However, when I challenged the remarks, I found the source/reinforcer to be the contemporary United Church of Canada.
