I have commented before that a lot of young people from the ASL congregations are doing street work here in long Beach. They just come out and stand there on the corner of 5th and LB BL. When you go up to them to talk to them they decline saying they are there only to talk with deaf people. One time I asked them how they know they are going to run into a deaf person just standing there on the street unannounced. They say that they run into deaf people "eveery now and then." I told them there are a lot of better ways to talk with deaf people other than just rolling the dice and walking out on some random street corner. they didn't seem real interested in finding ways to actually meet deaf people.
I think that there are two things that make them prefer to just go out and stand on the corner. One is that they can get in a whole lot of hours by just standing there in a large group talking with one another, plus they stay encouraged as long as they are with their fellow JWs. So maybe tyhat's a third reason.
the other reason is they probably think Jehovah is going to magically send them the right deaf people no matter where they stand or go. So they are pretty confident that it just doesn't matter is they use a metghod that is effective or not. Going to the north pole would make just as much sense to a person who believes that Jehovah is going to send them the right people magically.
On a side note, I think it is sad that the Watchtower Society is targeting people with special needs on the selling point that they will be able to hear one day right here on earth. Plus I can imagine that deaf people might miss out on communication through some channels that would inform them that the Watchtower is a scam. So I think they are more vulnerable than some groups, hence, the Watchtower pounces on them and takes advantage of their free labor.
