Another study shows it is minorities who HATE the most, NOT whities. So, google and FB,... are using AI that identities HATE speech that will result in banning black people. NOT what they expected.
In my dealing with a variety of people I have learned there are no tribes that do not look down or even hate other tribes. But, the problem seems especially egregious among the majority tribes who maintain their status by pushing out others they deem below themselves. It is natural and common among most life forms. This is even evident among invasive plant species. Hmm, guess that makes some human tribes invasive.
