Great questions, I don't know any of the answers.
The vote was 61-39%. There were ‘more than 1460’ delegates. Don’t know if all of them voted, I would think we would have heard about abstentions maybe? Not sure if every unit/charter group sent delegates if they had the option to do so.
You would think that at least some of the Scouting units/charters/whoever who voted against it would give details of the rules. Was it a secret ballot, is there some kind of privacy policy or something about these details.
All the searches I did seem to be drowned out by stories about the controversy, one thing I did see was the policy of the boy scouts for choosing youth delegates, which I assume is something different.
