To be fair, Mafia isn't really an aesthetic, its more just a common name for Italy's (later on America & Italy's) powerful organized crime groups ran by Almost exclusively Italian & Italian Americans. So, in reality the "Mafia" Aesthetic can more-so be seen as an insensitive stereotype of Italians & Italian Americans. Which only gets worse when you realize many Italians immigrated over to avoid these organized crime groups.
As an Italian American though I personally only get annoyed when this aesthetic is used excessively, I fully understand why other Italians & Italian Americans can be annoyed much more then I am.
And now im thinking the original tweet was made by an Italian American whose family was heavily affected by said organized crime groups......
