Exactly. People are taking it way too serious. It's a funny picture done by a fan no doubt. It's not even like Rakim signed it "Fuck Tech N9ne" either. Someone takes the time to do a painting like that and wants the artist to autograph it, any artist who cares about keeping hardcore fans (who put food on their table) will sign it. I'm sure Rakim would've signed it just the same if Tech's head wasn't on it.
Rakim is a Legend, he's a reason that emcees like Tech N9ne exists today... I'm sure Tech had at least one of his albums, if not all of them... I think it's pretty funny that ya'll get butt-hurt over shit like this...
