Why use the loaded word "cult?"
India is the second most populous nation, and is close to 80% Hindu. Are they all cult members? Just asking, and not being snarky, because that's a key idea.
It's fair to criticize a person's policies and actions, but to bring up how a person is raised because it's different isn't an American Value. 
Sure, I remember ISCON and the Hare Krishnas in Waikiki and at the Airport during the 1970s.. Sure, I thought it wasn't cool some of the things I had heard they were doing to their members. Hawaii was still pretty naive. But people, and societies, do grow up. 
Religion is religion. Just because it's different doesn't make it wrong.
BTW, I'm a Deist, not a Hindu, who largely accepts that there is a supreme being, but rejects the supernatural nature of an activist God or gods.
There's room for all of us in the world.
