I haven't found anyone who sufficiently tackled this subject either. I think a big issue is finding people who are into alternate information who are also into (or were into) hip hop. I think just the topic of lyrics from the music alone is worth a study.
One idea that has been circulating around in conspiracy is that part of the current direction of (corporatized) hip hop is to make men more feminine. I've noticed this lyric on Jay-Z's song "Family Feud" off of the album titled "444".
"And old niggas, y'all stop actin' brand new
Like 2Pac ain't have a nose ring too, huh"

If we entertain the emasculation of men idea then I think that this line is to give a pass for rappers who wear women's clothing (like
Lil Uzi Vert and
Young Thug). Even Lil Wayne aka "Weezy Fucking Baby" has a
weird relationship with rapper Birdman (Baby). In this
video, Lil Wayne claims baby is the only man he kissed... Kind interesting considering the fact that Birdman supposedly raised Lil Wayne and was his father figure (incest?).
I'm not sure if you've heard, but Africa Bambaataa has been accused by three men of molesting them when they were younger. At least in "official" history, Bambaataa is known as the founder of the Zulu Nation which defined the four elements of hip hop: rapping, djing, b-boying, and grafiti art. Kind of strange that the "Amen Ra of Hip Hop Culture" is accused of being a pedophile. There are interviews with one of the alleged victims Ron Savage on
youtube if you're interested.
