Rivalries
 

Is the rivalry between PrinceHall Masons and Black AF&AM Masons, similar to the Greek Rivalries like Sigma's vs. Kappas, or AKA's vs Deltas?

I know PrinceHall Masons who say AF&AM's aren't legit.
I know AF&AMs who say PrinceHalls promote hate within the race by dissing fellow Black AF&AM Masons.

Is it just a rivalry or is there some substance to what they say about each other?
