I don't think you have. So some people got gains, on the communications course, so what, did they achieve clear or OT? So some of Hubbard's policies tell you how to run a business, so what, many other people do too,I've given you some pretty clear examples of things that don't constitute persuasive speech (or writing) and you've done nothing to refute what I wrote.
The bottom line is nobody went clear, OT, or returned from past life. In the end it is all rhetoric to persuade one to go up the bridge.
