The matter is only an "un-merge" discussion, because you proceeded rapidly to delete the page and accomplish the merge—knowing that I, a newcomer to the matter, had sound editorial objections. 

 And, apologies for marginalizing your clear lawyerly concerns, but your behavioural lectures are lost on me, despite your ability to quote chapter and verse. You ignored repeated lower case attempts to engage you in dialog, asking you clearly, "allow discussion to continue." Instead, you proceeded to delete the Foundation page despite being asked explicitly not to (because it would confuse the discussion for new incoming parties). And you wonder why on asking a final time for you to not delete the page, I resorted to upper case to get your attention?

 Moreover, and critically, I saw how you treated the independent, novice editor that tried to engage you in the initial deletion/merger discussion. Your zealotry for article purity confuses both technical issues (are there any citations, and are they good enough), and overwhelms your commitment to WP standards of treatment of young editors, clearly. I have as much or more experience, professionally, and here, vis-à-vis judging the quality of organizational sources, and science organizational sources. The quality of sources for this foundation—sources you did not bother to find—allowed me to begin taking steps to improve the article. You bulldozed past these, clinging to the legality that you had the permission you needed to delete, and so disregarded and disrespected two fellow editors (at that stage, still communicating in lower case).

 So forgive, if I say, your WP:THIS and WP:THAT, however legally sound it might be, in spirit rings very hollow.

 I have stated my "peace". Please return the Foundation article to the main article space, so that all editors, experienced and inexperienced, can easily find it, so that the merger can be discussed, and a final decision made. Or as I said, budget time for explaining this all to a group of impartial admins and fellow editors. Cheers.  Le Prof
