Are people cult-aware?

Here's what I just found about cult techniques - "If you receive such an invitation from your child, you've been given a valuable but risky opportunity to help your loved one escape. Once you're at the meeting, the cult members will probably try to isolate you from your child. This separation can be accomplished quite subtly: One minute you're sitting next to each other; the next minute, each of you is approached by a cult member who engages you in separate conversations, gradually moving away from each other until you're physically across the room from your child."
