Are more likely. Are 'considerably' more likely to hold anti-semitic views. And the more right wing you are, the more likely you are to hold those views.
The survey states people who identify as 'very right wing' are 200-400 percent more likely (2-4 times more likely) to be anti-semitic. It also states that right wingers in general are ''considerably'' more anti-semitic (without giving numbers).
How is that 'largely; not that different?'
Comprehension mate. Try again. The survey you posted states:
1) Left wing people hold much higher negative views of Israel than people of other political leanings.
2) People who hold negative views of Israel tend to also be anti-semtic.
You're then concluding from those two statements that left wing people (who hold such strong anti-Israel views) must thus also be much more anti-semitic.
Yet the survey concludes that left wing people are no more anti-semitic than the general population despite holding those negative views of Israel.
Go and have another read.
I seriously don't get the fuss about it, and totally don't understand why people are anti-Semitic, other than maybe they have their own religion which is at odds with it.
The survey concluded 25% of the population agreed with "at least one" of the anti-Semitic statement. The overall population classed as Anti-Semitic is 2.4%.
So in the right -to extreme right wing groups, it would be 5 to 10%. So if you grabbed a single extreme right wing person off the street, its not "likely" they will be anti-Semitic, is a 1 in 10 chance.
Would be also interesting to see how the questions are formulated.
