Here's an abbreviated answer to your opening question from my historical perspective (your mileage may vary):
Long ago, back when Chuck Russell was still around and doing his jellyfish thing with all the babes, Chuckie was cheesed over the fact that he wasn't triumphing over his opponents in his once-famous "public Debates," so Chuck issued a general order to all his "Pilgrims" (salesmen) that it was a waste of time to debate religious foes.
One of Chuckie's boys, Joey "Da Judge" Rutherford, gets this smart idea in April 1915 and decides that he will ignore Chuck's standing order and go out to California to debate Baptist preacher J. H. Troy over four nights before an audience of 12,000. Rutherford got his ass kicked and when he returned to Brooklyn Bethel he found Chuck rather displeased with the mega-flop and Rutherford began the oblivion spiral. Then on Halloween Russell recieved his reward and Joey's friends in Bethel called him back to Bethel to stage his coup.
"Say 'Hello' to my little fr'ends" he is reported to have said as he pointed to his trousers.
