Folks here know I'm generally socially liberal. And my take is, the BSA were morons for giving in to demands of an extreme minority of marginal scouts. Yes, I'm aware it's hard for an organization to fight off legal battles of dozens of angry activists. But they should have dug in their heels. WHILE offering to help support special scouts for whatever niche group. "You want Scouts to accept Apache attack helicopters as a valid alternative gender? Fine. You're now the Apache Helicopter Scout Troop #1. Have a nice day. Insurance premiums are $10,000. Due net 30 or your chapter is disbanded."
By giving in not just to SJW but every Safety Gestapo and Tile Crawler Sue Happy lawyers to serve them papers, they gutted themselves. They could have tried to get a legal shield, like the gun manufacturers did. Instead, they caved and caved and caved. Until except for a handful of well led troops, their numbers dropped like a rock. Lawfare and poor leadership killed the Scouts. I'm sure the name and brand will survive for couple more decades.
Freedom of association sure has taken a beating over the last couple decades. Take any association with any substantial meaning, and try to reduce it to the lowest, most meaningless common denominator while crying a river over individual edge cases that couldn't make the cut.
