Deletion of Walk-in

Comment: as a  concept which gained a lot of traction from Ruth Montgomery's 1979 book ''Strangers Among Us''. Somewhat harder to find citations since the phrase to "walk in" is widely used in the normal sense, but making it plural might help in finding sources, also adding the phrase ''ruth montgomery'' to the search is helpful. Also, the nominator's statement "Previous PROD removed by IP editor without any given reason" is false; the IP said "''but some other references do include the term, and it needs explanation on wikipedia, i came here looking for it. if you can improve the article go ahead, but don't delete it''". Anyway, I've just added six scholarly citations from notable new-religion scholars
