Since we're always dealing in hypotheticals of "if it helps just one person then it's worth it", what if instead of helping anyone it takes one person that was on the edge of leaving and scares them back in? If you're going to ask the question, might as well consider it both ways.
I do think everyone responds different to different things. But if you're going to insert yourselves into the lives of people you don't know forcefully, it's sobering to think that you could actually help the cult more than hurt it by choosing a way that fills your ego but might hurt another person in the audience.
