stillthinking,
I am going to go ahead and answer what you posed as a rhetorical question - i.e. "How many times have you had a face to face conversation with someone telling you the good news about Jesus in a public place?"
That used to be a common occurrence in Central Christchurch during the mid-1970s, and it was by no means unknown there during the decades after that, either. (When I lived in Christchurch between 1997 - 2001, they were still active about the CBD most Friday evenings). Also, these ones actually talked about Jesus, rather than merely attempting to offer literature (and little JW literature has much to say about Jesus, let it be noted!) Furthermore, unlike those ones mentioned by NewChapter, none that I recall ever sported the "Thousand Yard Stare."
As for calling "when they are at home"; very much in the industrialised countries, the only time people are at home is at night. Call then, and you only succeed in frightening them (I had several such bad experiences like that, thinking - like you were suggesting - that I was doing the right thing by calling when they were home, only to have people think that I was a home invader).
Mine was not the only experience like that, either.
Bill.
PS: Like you, I no longer believe in a god of any sort, either.
