It depends, the key is to dial it up or dial it down, the same game doesn't work on every woman. However, if a dude has his game on point in NYC, LA, London, etc. it's easier to pick up these down south girls. Almost unfair.
They promote game and use the same tactics pimps and players do.
The difference, and the reason these dudes get so much flack, is in the packaging. Lot of these dudes come across as corny white dudes, nerds, socially awkward chumps, and so on. They don't come across as smooth and socially validated, don't seem like dudes you would ever hang out with.
I can't hate on what they're doing though, you shouldn't have to fit a certain look to get laid a lot.
