The decision to start girl troops perhaps, but the homosexual allowance is what cost them millions of members.. which is why they are going bankrupt.
Mormons pulled out once they made that announcement, which cost them a very large segment of their membership.. something like 2-3 million members if memory serves.
This was driven by one guy on the national council, can’t remember who it was, but he destroyed the scouts....
It was a terrible move that put millions of boys at risk from homopredators, but in my area the Scouts were already becoming a thing of the past. If anything, allowing gays convinced the foreign “replacement Americans” that they shouldn’t get involved in scouting.
Peers who involved their children in it (boys and girls) were turned off by the focus on fundraising instead of actual activities for the children; they didn’t remain involved for long (and that pre-dated the gay thing).
