So looking at Kanye West's actual Tweet, here is what I can decipher.
Kanye says his cousin is serving a life sentence for murder and he and his cousin found dirty magazines where they acted out on what was shown in said magazines. Kanye and his cousin finding their parent's dirty magazines isn't really a crime (long before the Internet as we know it existed, if some kid wanted porn then they just dig through their mom's or dad's or brother's porn stash to see some naked people; that's not a crime that's blatant irresponsibility and interference by the owner or said porn where they failed to put said porn in a secure location where no kid can have access to). What is a crime is sexual battery.
My best guess is that Kanye's cousin was likely the aggressor since the only thing I know about the cousin (according to Kanye) is that they murdered a pregnant woman so if the cousin is capable of killing a pregnant woman then the cousin is also capable of sexual battery (evil kids unfortunately do exists, evil knows no age).
So my best guest is that the cousin forced Kanye to perform the indecent act on them because the cousin wanted to feel powerful (serial rapists and serial killers like hurting people to feel powerful).
So if what Kanye is saying is true then Kanye may likely be the victim and his cousin is the culprit that forced Kanye to do such a horrible thing.
Granted this is something about Kanye's personal life no one needed to know (please see a freaking therapist for Christ's sake, the public doesn't need to know about the darkest moments in your life). But if this is the case of Kanye actually being a victim of sexual battery then once again it proves my theory that Jersh is a sociopath. If Kanye was a child sex abuse victim then nothing about this is funny, his cousin committed a heinous crime and Kanye was the victim in this case. There's a lot to criticize Nick Fuentes and the Groypers for but this isn't really the gotcha Jersh thinks it is.
