Membership has been declining for several years. I think part of that is the less attractive aspect of Boy Scouting as being “low tech,” outdoors-oriented in an age of air-conditioned indoor technology. Also, it has become politically incorrect to refer to Indian - oops, I mean Native American - culture in any regard, and that is a consistent theme throughout Scouting. (Indian Lore merit badge, Order of the Arrow, etc.)
This latest change has not reversed this decline. In fact, it has accelerated it.
You make good points.
But I would ask, at what rate is it declining?
If it is precipitous, it’s not just the unPC parts of it. Maybe it would include the homo acquiesence. If it is slow, likely it is mostly just not hip enough.
