The next step is being inclusive of nonreligious agnostic and atheist youth and leaders.
Technically, they already are, with the possible exception of nihilists.
The scout oath does include a "duty to god", but they do not define what they mean by "god" or "religion". Instead, they explicitly leave those definitions to the scout.
The only requirements they actually have on the subject of religion is 1. tolerance for the beliefs of others, and 2. "reverence" for your own creed.
Under their policy, "the laws of thermodynamics" is a perfectly acceptable "god", and "In this house, we respect the laws of thermodynamics" is a perfectly acceptable "religious" creed.
"The environment" is a perfectly acceptable god, and "we must preserve and protect our environment" is another perfectly acceptable "religious" creed.
I readily concede that their policy is needlessly complex. It would be easier to just drop the "duty to god" and "reverent" requirements entirely.
