Beg, beg and beg some more, you'll get to stand up and relate even more. that's all it was, just a bunch of bullshit throwin the dog a bone mindfucking horseshittin compliance mongerin psychophysical abuse. No roots or nothin else, just plain ol' BULLSHIT to make kids look like retards for the perpetrators pleasure. :
You are dismissing a phenomena that crosses over not just from our particular groupthink, but into all
other groups where submission to the group is deemed essential for advancement or to gain status in the group. It crosses all boundaries from cults to religion to 'rehab'.
To dismiss it as just a device to make you look silly is looking right past the actual reasons for motivating. I suggest you watch the video again and give it some more thought.
BTW, not motivating could get you standing up as well, but not doing it was an immediate identifier of someone not in submission. So, motivation serves several purposes in mind control. Notably, 1) self-submission to the group and 2) an identifier to others in the group that you are in submission and part of the group identity.
