I reread WP:SELFPUB as you requested.  It says:  "Self-published or questionable sources may be used as sources of information about themselves, especially in articles about themselves, without the requirement that they be published experts in the field..."  PATH may be used in an article about PATH, but it may also be used when discussing PATH.  Also, the deleted material was a discussion about the freedom to talk about SOCE, not a generic essay on freedom of speech.  It is directly related to SOCE.  Please leave the article as is before creating major changes.  Please review Wikipedia:Editing_policy#Be_cautious_with_major_changes:_discuss.  It says "With large proposed deletions or replacements, it may be best to suggest changes in a discussion, to prevent edit warring and disillusioning either other editors or yourself (if your hard work is rejected by others). One person's improvement is another's desecration, and nobody likes to see their work "destroyed" without prior notice. If you choose to be very bold, take extra care to justify your changes in detail on the article talk page. This will make it less likely that editors will end up reverting the article back and forth between their preferred versions." If you continue to make large changes to this article without first discussing them, I will refer you to edit-warring board.
