For what it's worth, I grew up in a town that was roughly half jewish, reflected in my circle of friends. When I was younger, extremely crass jokes that made light of historical tragedies were made at everyones expense, including ones that historically affected my family. It was clear that the intent of these was not to instill terror or provoke hatred. It was more of a pissing contest, to see who could say the most absurdly offensive thing.
Were these the types of situations where we should have had more sensitivity to the real weight of these tragedies? Sure.
Were these hate crimes? Absolutely not. When someone commits a hate crime against you, you probably wouldn't regularly invite them over to your house for the next several years...
