Ok, how often do you see Hindus, Buddhists, Nepalese, Indians, Thai, Mongolians, Sri Lankans, Chinese, Japanese, Akans, Hopis, Navajo, and Tlingit peoples spray paint it on walls or get it tattooed on their bodies in AMERICA? This isn't any of those countries you listed. The next time I see someone with a swastika on their neck and a Nazi salute here in America am I supposed to assume it's a peace loving Buddhist with an interest in Roman history?
He stole it from the Italians under Mussolini, who basically took it from a painting. There's no evidence the Romans used this salute, so it's always been associated with fascism.
