Maybe, but FARC and Shining Path are far less familiar to Americans, than other criminal organizations like the various mafias, prison gangs, street gangs, and racist organizations in the US.
So while ISIS has a different ideology, history, and objective than that of Los Zetas, Sinaloa Cartel, CDG, etc they are more similar and comparable than other, more familiar criminal organizations.
La Cosa Nostra, the Russian Mafia, and the Yakuza, to my knowledge, don’t regularly record their murders for the purpose of distributing them to the public. Nor have I come across large scale mass murder committed by those groups in recent times.
The Mexican Mafia, Aryan Brotherhood, Nuestra Familia and Black Guerilla Family are mostly behind prison bars, and usually when they make the news it’s for drug dealing, or killing of their own members.
California, Chicago and NY street gangs make videos but usually it’s just trash talking or at worst, filmed fights or beatings. Never murders on tape, or large scale mass murder, or the taking of entire towns and cities, although neighborhoods have been taken over.
The Ku Klux Klan is very vocal but seem to be reduced to a particular message board and the occasional news story about racist marches or speeches, and once in a great while a hate crime directly attributed to an white supremacist organization.
Some of the drug cartels methods seem to be more in common with ISIS than that of other North American criminal organizations.
