I dont think its fair or even possible for someone who doesnt know Fatal personally to "revoke" his "gangsterness".
I know people who can be really silly and childish, but in the next moment taking a kitchen knife, running around in the street and try to stab a person. Its not like you lose gangster-points if you act like a moron.
Sure its kinda stupid to diss a website, it would have been sufficient to say "Rukas, dont fuck with my money!" if he truly has a problem with it. Nevertheless Ill check out his next album, I like his style and hes the only good Outlaw left.
