Hinduism is a big problem. The Ganges is literally a river of shit - it has 120 times the safe level of fecal matter. Yet Hindus regard it as purifying and it's considered holy to have a dip in it. When you have a culture like that, it's going to be hard to persuade people to not shit in the water they drink.
True. The Ganges is probably one of the most disgusting things on earth. If your religion involves worshipping (and drinking of) a river full of poop and bloated human corpses, I couldn't justify it as civilized even if I tried.
