Certainly, there have been incidents, no doubt, but the frequency is a matter for official agencies to publish.
Also what everyone needs to keep in mind is that ANYONE can report ANYTHING to police and get a report.
It does not mean it actually happened. It just means it was “reported.”
I've decided this Southern Poverty Law Center is a swindle, collecting buckets of money by frightening elderly red-diaper Jews with lurid tales of their battles against the neo-Nazi boogeymen.
