When Immigrants come to the United States, they quickly pick up the social hierarchy and due to ignorance and inexperience with American society in particular, they view it as a social game and nothing more.
What the realize is that to make sure they do not end up at the bottom of the social totem pole, they put their feet on top of the perceived bottom groups, Black Americans. So in order to fit in and assimilate into American society, they know that shytting on Black Americans is a seemingly winning ticket.
However, they are so foolish in not realizing they are used at most as political pawns by white supremacists and they are expected to maintain subservience to the overall white power structure. Do not challenge and do not question the narrative and power structure.
Eventually they all get their wake-up call, but black immigrants will definitely get the most stark wake-up calls.
Either, they realize their mistake and overcompensate, or they experience extreme cognitive dissonance where they either cope by ignoring and continuing their lackey role or they do this weird mental gymnastics where they feel the institutionalized racism is wrong but still practice their role as being a buffer between the white supremacist ideology and black Americans.
I know a doctor who worked with a Chinese doctor that epitomized the former. He told her that he didn't mind when a white doctor strictly referred to him as "Chinaman" every time he saw him, and not in a joking manner either. He told the doctor that "he didn't mind and that he is just kidding around" while continuing to be an apologist for the conservative whites that mostly made up their area.
Pathetic.
P.S. Didn't watch but 30 seconds of the dude in the video. He is an idiot.
