Let's put this into perspective: When we talk about underserved populations in developing countries, we are talking about people who are living on less than $3 a day. They may have never had a formal job and most likely have, at most, a high school education. They don't have a bank account, they may live in a slum, and they may not have enough money to eat three meals a day.
Many UU leaders and quite a few individual congregations have openly moved away from viewing a humanist approach, free from theistic declarations, as the appropriate neutral philosophical place for all UUs to convene. It hasn't gone unnoticed, but the issue rarely gets addressed directly and openly. It's time for that to change.
