Hi Matrix: Thanks for the post. I have seen open discussions when I was a JW ... mostly discussing congregation financial needs, a vote on KH remodel work, meeting times, or at times the needs of the elderly or infirm, etc.
The Elder you quote at least is making a fair and honest effort. Not all JW Elders or congregations are bad, and a number have good decent people running them as best they can under the constraints of the religion's policies.
It could be that this particular congregation has not had to deal with a pedophile in a long time, and so they have literally nothing to hide or be concerned about.
What is of interest to me is how they will handle any follow-up private questions that Elder H invited from the audience ... regarding any past handling of JW pedophiles, or the Dateline program. That may be a better test of the intentions of the Elders.
