If you're perfectly honest, you'll come to the realization that those Dirty South niggas have supported some of the most garbage niggas the industry have ever seen, everybody from Master P to Gucci Mane. Southern niggas have not only supported these wack ass muthafuckas, but will argue that these dudes possess lyrically ability. It's enough to make you say "Really nigga."
Every region has it's garbage rapper they support. In New York, it's Lloyd Banks and French Montana. In the Bay, (where I'm from,) unfortunately it's $hort, as much as I hate to admit it, lyrically $hort always left something to be desired.
But it seems in the South, for every Andre, Devin, T.I. and Scarface that comes out there's like five Gucci Manes, Wacka Flockas, Soulja Boys, and Juicy J's. I can't figure the shit out because it isn't like those niggas don't know what lyricism is, hell some of the best rappers in game came out of the South. I think it's a damn shame when these niggas support garbage rappers it shits on the legacy of lyricists, their contributions to the game, and makes an entire region look like they don't have any taste in rap.
