You have no doubt heard about Cosanostra, the Gambino Family and the likes aka "The Mafia" would you say that the Italian culture is rotten to the core due to the notoriety of the mafia.
Have you heard about Mara Salvatrucha, commonly known as MS-13, does that make the latino culture rotten to the core?
Depends - do the entire communities defend those criminal gangs and rally round to protect and excuse them, to deny the violence they commit?
For some reason, BLM types always want to do this with black crime even though the victims of those crimes are very often other blacks.
I judge people by why they do and what they support. If people are supporting criminals, whatever their color, then I think they are criminal too.
