Well, it varies based on the target racial or ethnic group, depending upon which ethnic group is currently the darling of the American "Progressive" Left.
I'll illustrate:
Here, we'll play, "Let's Define a Hate Crime!"
Others are free to offer examples which might help clarify.
But the point is, in comparing the numbers of "hate crimes" allegedly committed against Jews or Muslims, it's useful to remember that a "Hate Crime" against a Jew pretty much requires Mass Murder or significant Arson or both; but "Hate Crimes" against Muslims can be understood to include acts which are, you know, hurtful to their feelings and such.
Hope that helps.
Should have said "religious group" or "ethno-religious group"; Muslims are not uniformly Arab, albeit the worst of the Wahhabi Muslims generally are.
Other than that, same point.
