Update: Been there done that a couple years ago, no improvement. You're exactly right, they be pretty much conditioned to hate whitey w/o cause.
I’ve been the only white guy at numerous black functions and have always been well received. At nearly all these functions the black attendees were overwhelmingly Caribbean. From my experience, both Caribbean born and African born black people are generally less adversarial to white people than American born black people. And, of course, the stigma of being more adversarial does not apply to all American born black people.
