So what they have is 10,000 random people worldwide who they called out of the blue answered negatively and have used this to state as fact that one fifth of the world's population is antisemitic.
This has been used to support such headlines as "ADL survey finds one billion anti-semites".
Now I wonder if such a survey were done for other groups of races or nationality or gender. I bet the figures would be AT LEAST the same. But you probably don't see what I'm saying.
Can you imagine that one in 5 men think misogynistic thoughts or 1 in 5 Britons would respond negatively to questions about immigrants or travellers. It would be at LEAST that.
Is it OK... fuck no!
