90% of discrimination against Jews in the US is because those Jews appear to be white, male, and/or are not sexually deviant.
9% comes from Islam. This is growing with the number of Islamics.
The other 1% is what the ADL was actually set up in the first place to fight. But it’s all but nonexistent now and any remaining prejudice is all but moot.
Much of the ‘anti-Jewish’ online activity is by left wing trolls posing as Nazis. See a lot of that on 4chan.
Certainly there are a couple hundred Nazis in a country of 300 million. Typically the average KKK march is half FBI agent infiltrators and a dozen actual racists. More protestors appear at the marches than marchers.
But the Left is all about creating the myth of ‘hate groups’ so they can continue to play the victim card.
