You’re absolutely correct that equality and rights have progressed tremendously for blacks legally and quite a bit socially. I think it’s purely socially that many Americans are still seeing the inequality though. An embedded stigma or ideal of black Americans that many white Americans still vaguely refer to as “niggers.”
“Not black people, but actual niggers”
Very loose and individually varying definitions as to what an actual n***er is. For many, that simply means those who partake in unacceptable or ignorant black behavior. Once more, very vague.
Rarely do these white Americans refer to whites as a n***er unless, they socially behave like an ignorant black. White criminals don’t seem to be referred to as such generally speaking (granted, they usually receive equal disgust). What many white Americans define as n***er behavior never really is called that unless the perpetrator does something ignorantly shameful (not always needed either) and they have a strong connection, similarity, or influence towards black culture.
Not the ignorant criminal behavior, but simply fashion, mannerisms, dialect, location, or social behaviors commonly associated with black stereotypes in general or actual urban black culture.
It’s usually not the ignorant behavior that makes someone a “nigger” it’s actual black culture that is viewed as “ignorant behavior” to many Americans. It creates a sense of inferiority which views anything that blacks do that comes from within the communities own innovative social evolutions that does not stem from European or white American culture as inferior or intolerable (let alone acceptable).
Of course there are some vastly accepted (not just tolerated) cultural differences or social norms. Very few, but still some and even those are not accepted as whole.
For the most part, the less you behave as a black and more as a European the greater chance of being vastly accepted as a “black person, not a nigger.”
It’s a lot to truly contemplate and to challenge your way of thinking to see a deeper perspective of what’s socially acceptable and what is truly demonized in America’s mainstream ideologies.
It’s not about what’s allowed, but who is acceptably allowed to do it.
