There is a lot of anti-blackness in the black community from those perhaps meaning well but it is anti-blackness nonetheless and needs to be eliminated. It is understandable to hear this anti-blackness among people those who do not claim to be and are clearly not conscious of the various manifestations of racism.
I blame most of it on the anti-black media programming coming from white people who control 90% of global mass media of course utilizing the talents of their non-white employees to help push it.
I blame some of it on intentional deception in order to manipulate people into supporting an agenda.
I chalk up some of it to people simply not reading enough and not knowing the definitions of the words they are using.
Culture: the arts and other manifestations of human intellectual achievement regarded collectively.
Achievement: a thing done successfully, typically by effort, courage, or skill.
Sub-Culture: a cultural group within a larger culture, often having beliefs or interests at variance with those of the larger culture.
