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.
24 hour news is worse for this than gangster rap and turned off both so the same reason, I didn't like the messaging coming from it. NWO and Ghetto boys pushed me out of the genre, that doesn't the music is bad just something I choose to not engage with based off their content.
You got super defensive over what should be obvious, the content and people you engage with will define your character.
Surround yourself with positive, talented people to keep your mind clean.
Hell even vogue and trash mags call out 'energy vampires' (lol) but it's all the same thing.
I legit decided to not listen to gangster rap in the 90s because a dude said to me 'that shit will warp your mind ' but I realized all music and influences do that.
So books it was...god I was a nerd!
I cut the cord on much of it early on, mostly because the value was terrible (aka music industry in the 90s was just bad value).
Now it's the odd anime that had a deep story that pulls me in...and lectures..Holy fug I love watching smart people talk :)
