You can try the Unitarian Universalist Church website which welcomes all faiths, and I do mean ALL. It's a very welcoming group located all over the U.S.
That's a great suggestion, White Dove But I do not think it helps our friend deborah, as she has implied that she would prefer to discuss topics with only ex-jw, non-trinitarian christians. With the Univeralists open-minded way of accepting people of all faiths, she will probably encounter people that do not share her beliefs and who promote the trinity doctrine.
