Moonies used to be a big deal at college campuses in California. When my husband and I went to Berkeley in the 1970s, the Moonies were everywhere. They did many questionable things before fading away.
My husband is 4 years older than me - so he was not as aware of their recruitment practices. He said he was invited to dinner by a very attractive young woman who kept flirting with him all through dinner. She then invited him to a weekend retreat. He said he became suspicious and did not go. It was a good thing he did not go. By the time I went to Berkeley - we all knew about the retreats.
