When it comes to the whole black rapper 'gangsta' thing, it definitely bugs the hell out of me too. I'm not racist or anything, but I don't like seeing a bunch of black guys rapping about pimping hos and all that shit associate with the Godfather.
There's more to the GF than just crime, and it's evident in the movies. There was class, there was honor, there was Italian pride and family orientation.
This has bugged me for a while. I have friends at school who can't see past certain generalizations so some of them figure that I am into the 'gangsta' genre since I'm known as a GF fanatic. In no way is it true. I am more old fashioned, and my parents make fun of me because they say I act and talk like an old man in several instances.
I guess this is the clash of street violence with cosa nostra. You've got gangs, those like you'll see in places throughout inner-cities, then you've got families which are displayed in the GF movies. These two have been clashed so that the 'gangsta' genre is smeared into the GF movies. That's why whenever I hear about gangsters like Don Corleone and Al Capone, both fake and real, being considered 'gangstas' with the black street pronunciation, I correct who ever missuses the term. There are two different concepts, gangstas who make their way of life by living a tough life on the street, often involving drugs and prostitution, then you've got gangsters, the actual wiseguys who make a name for themselves and see crime more than just something to rap about, these wiseguys have stuff organized, and have a strong hold over some areas, often having more influence over law enforcement and not being brought down as easily as these street gangs. You'll get more out of a famiglia than you'll ever receive from a street gang.
That's my take, they can have Scarface, that is a gang movie. However, just because Pacino acted in both (and did a great job in each), GF should never be so associated with SF, they are two different styles.
