Maybe I don't understand the question but of course a persons lived experience affects them. It seems like you've moved the goal posts.
What I'm pointing out is that OPs moralizing on good media "Anime, Books" vs bad media "Rap, Trash Magazines" is likely focusing on the wrong things. A person's friends are ultimately what matter in prioritizing values (as far as values can be shaped by environment).
But the claim about "gangster rap" (a term I don't like) was "that shit will warp your mind." is false. Moreover, Anime has tons of content that's way darker than anything you'll find in rap. But again, I don't think it really matters.
