Well most entertainers that throw "illuminati" and "Freemason" "signs and or symbols" are black. I happen to know on excellent authority that blacks aren't allowed to be Freemasons, so.....I think it's cultural appropriation. The FM and illuminati are really popular conspiracy theories, they just do this because people will notice (it's so obvious that's how you can tell they aren't members). People see jay z an Kanye throwing up signs and buy their shit music to discover the secrets of the illuminati, which aren't in there other than a few symbols they show on album covers and at concerts. The one they show are the most well known ones so it draws attention aka publicity.
