What this American Black culture is? Selling drugs and promiscuity isn't exactly culture — this is just what poor people often do and a lot of black people just happen to be poor.
And while there sure is "gangster rap", there is quite a lot of hip-hop music criticizing "gangster shit" (the term itself didn't appear out of nowhere) and how it's romanticized — they don't consider it "culture", they consider it a huge problem for their communities, take this album by Master Ace for example: https://mastaace.bandcamp.com/album/the-falling-season
It's about his high school years, and about being smart enough to understand that he deserves better, about wanting to be a normal school boy, not being involved in typical "nigger shit".
But being critical of something doesn't necessary mean that you hate it, it often means that you want it to improve. Should I consider all Americans who are critical of US policy anti-american traitors? I don't think so.
There is this recent movie: https://en.wikipedia.org/wiki/American_Fiction_(film)
It's no masterpiece, but it's good. And it's not all what it's about, but it explicitly makes fun of this stereotype — that if you're black you are supposed to be a criminal and adopt particular slang and accent. But it's not about how these things do not exist, it's about how it would be hypocrisy for Black American with a middle-class background to claim that it has anything to do with him/her.
