I gotta laugh at this a bit because I never implied that and it says more about what you're thinking dude lol
I've read multiple "I'm an ex inmate from a max security" stories and the stories share a pattern: prisoners make friends, often of the same race. Based on the crime you committed, you'll attract certain friends/foes. A rapist will get raped. A white guy who killed a black guy is going to get ****** by a black crew. Hell, any white guy going into a prison is gonna get raped (or at least attempt) by a black inmate from what I've read. If I were a black inmate, spent my life getting racism tossed at me, and I didn't have enough self awareness to realize a lot my bad cards were from self-victimization , I would absolutely wreck every white guy that steps into a prison: this is the angle that comes from.
The above holds more true in maximum security prisons. Do some digging; you'll find plenty of stories.
EDIT: Btw, it's apparently common, in prison, to have an initiation check within the first day. This means somebody is gonna come kick the **** out of the new kid. If the new kid doesn't fight back, regardless of winning or losing, we know where he is on the totem pole.
