The problem is that the best separate organization for boys just recently bowed to the god of this world and gave in to homosexuality. Of course, judging from recent activity in gay pride groups, it wasn’t nearly enough for them. Boy Scouts leadership should have learned right away that it was the wrong decision, but that won’t happen.
I expect the BSA to implode - soon! When that happens, there will need to be a demand for the re-occupation of a 'new" OLD Boy Scouts by principled former scout leaders. To create alternative organizations will lessen this demand as boys and their families will be preoccupied with their new organizations. Also, creating alternative boys' organizations will just create new targets for the highly emboldened homo-Nazis to attack. And attack, they will with vengeance.
There is nothing more effective than taking back ground from the enemy. It completely demoralizes them and bolsters the defenses of the ground regained by conservatives. Rest assured, if traditionalists retake the Scouts, there will be very little change of it falling to leftists again.
Just my opinion.
