We had a decently sized group in one of our congregations.
They complained they felt they were treated as second class JW's, partly because they used the library and were not mixed in with the front group.
Are thoughts were never that, but it was distracting to the regular group, having someone standing up, interpreting in an animated way, and by using the library, they had the possibility of interacting while a talk went on for clarification. No problem, so we switched them to the front.
The Elder that lead out group said they learned ASL because of a relative who was deaf AND it gave them an opportunity to get away from the regular boring meetings. It was also a great way to gossip to each other in public with no one knowing what they were saying.lol
We also had a unique foreign language group that used the 2nd school room. We asked them if they wanted, we could move them to the front and use head phones. They refused saying, they needed to intereact as the talk progressed and needed a seperate enviroment.
