All the time. Its ridiculous, especially when many of those mafia cats were flat out racist. It goes both ways.
However, the situations arent the same. Here, we have European white guys imitating the lifestyle of the music they make. While they may not say the same things, the names, the artwork, the poses, etc...all influenced directly from the "g-funk" rappers from 15 years ago.
With rappers talking about mafia shit, they weren't dressing like mafioso or talking like them...sure, there may have been some themes on album covers. But they were still rappers, not mafia guys.
