I think I would counsel using a different organization for the boys under my care but at the same time retaining one’s membership in the BSA. The objective would be to keep that organization in contant turmoil, so it cannot be presented as some sterling program for boys.
IOW, I’d keep the wrecking ball operating within that organization. I’d want it to look unwholesome.
And, in the same way as the left always does, some conservatives should be sleepers in the hierarchy awaiting the day when they are in a position to steal the show back.
I know this sounds like just another nutcase conspiracy theory, but it makes no sense for the people in charge to be securing corporate sponsorships by doing what they know will reduce the BSA to a shell of what it is now. It's already far smaller than it once was yet rather than keeping the people that fill the ranks and do the grunt work on their side they're clearly working toward some other goal.
There's no way, again IMHO, that they'd be doing this unless they have a plan for filling the ranks again and know they're going to have plenty of help doing it.
I think a lot more than their caving in to political correct pressure and queers is at work.
