Because there are so many hate hoaxes in the national (or international) news, it’s worth noting that there really are a number of genuine hate crimes committed by white men each year in the U.S.
Typically, however, they don’t get much non-local publicity because they are so cut and dried: A stupid drunk white guy does something bad while drunk and stupid in a lousy part of town, the cops arrest him almost immediately, his lawyer plea bargains, and he goes to prison for awhile.
What tends to make the national news are “mysterious” hate crimes where “Fear Stalks the Oberlin Campus” and the like. Those have a very high rate of turning out to be hoaxes or delusions. (Delusions are a little understood category: e.g., a lady wrapped in a blanket on a cold night on the Oberlin campus is reported to be a Ku Klux Klan kleagle or a gust of wind blows over a Jewish ceremonial tent at Kansas State and it’s blamed on anti-Semites.)
