Well, technically Indians are the original AryansI can't imagine anyone in the U.S being afraid of any group of East Indians to the point those East Indians would be considered a gang on par with say the Crips, MS 13, Aryan Brotherhood etc. When you hear the word "Gang" in the U.S its typical to associate it with violence, intimidation and menace. Those are not elements that get associated with East Indians. When I think of East Indians I think of math students, 7-11 owners and cricket players. Little small, physically meek but studious people. They might have a white collar, finance gang out there somewhere in the U.S but no street gangs.
Second
Almost all of MS 13 is filled with Mexican Aztec type who tend to be physically smaller than Indians
Asking if there is an Indian gang is like asking if there is an Arab gang in America or Iranian gang in America or a Turkish gang in America
Indians in America are the highest per capita. They're not from the back holes of India
Ironically the word "thug" originates from India.
