Love this thread. Magnum you said it, and Carla.
Wt will make it sound like it was started as a grassroots thing. I remember someone on this site saying that the clapping was started by a bethel representative. I found RedPillDevoter on Reddit saying the clapping at his/her convention was started by a Bethelite:
Still recovering from the initial shock of what I saw. It only gets worse. It was told to me that the person that started the rhythmic clapping was a bethel commission member that was oversearing our RC. I have no words... I'm only in just because all my family is. I need to find a way out. At least some of my relatives are waking up and start making questions.
I did not hear of it, or see it, in the Midwest yet, but Wt may know the Midwest is usually trailing behind a few years. Sometimes they seem to know what they are doing, and sometimes they do not know their head from their arse. I could see them trying it, and the midwesterners not following!
