Of course. And the information tends to be readily available, from first-hand sources, so the charges of manipulation and exploitation don't hold. If one opens up one's eyes and ears, one knows within the first few visits to a religious/spiritual group what they are about. If one actually reads a book by a particular religious/spiritual teacher, they can quickly discern what that teacher is advocating and what's his religious/spiritual program.
There's a scene in the book "Wuthering Heights" where a young woman is fascinated by and in love with a man who doesn't reciprocate her feelings. He tells her directly that he's not interested, but she doesn't budge. He even tortures her dog in front of her, but that doesn't change her mind. Some people who get involved in religion/spirituality are like that young woman ... but eventually, they cry foul.
