They don't even know what their heritage really is, that's why they make up crap like Kwanzaa.
Most have no idea. Thats why I suggested the trip to Africa. One of the reasons it is such a huge failure is its feudal kingdoms that still exist all over Africa that being all the chiefdoms...one for the night and one for the day. There? in backwoods Africa? The chief owns all and drives all. Anyone who gets more friends/power/success than the chief has a huge problem unless they pay unto the chief.
Societally? They are programmed to bring down the upstart, to bring down the progressive thinker. They call it PHD, or Crabs in a Bucket...PHD? Pull him down....crabs in a bucket? same stuff
It's an understandable impulse. It's not their fault they have no clear record of their heritage and culture - they have a need to fill that gap and hucksters like Ronnie Everett are more than happy to do it.
As a man of Irish ancestry I have seen my fellow Irish-Americans indulge in some similarly ridiculous mythmaking.
