I've never been a missionary* and don't plan to start here. What other folks don't know ain't my problem, unless I care personally about them and their well-being. (Fortunately, my GF was into FF programs, though not quite as insanely as I am, before we met.) For that matter, the fewer people who don't get it in this regard, the better for the rest of us!
