The threat of ostracization (which should be recognized as a legitimate word, jfc) hangs over them like a Sword of Damocles.
The threat is not so much about ostracization as it is about being cut out of the credentialist pipeline.
If you get "kicked out," you won't be blessed with credentials.
To naive young people, this sounds like lost economic opportunity...
Titles won't matter.
Diplomas won't matter.
Only your experience and actions will matter.
And that scares losers to DEATH.
