I actually just heard a news story on the radio about this very topic and besides a drastic drop in membership or boys wanting to be boy scouts was also a loss in funds due to lawsuits from sexual abuse. Now I remember a while back decisions to allow homosexuals to be troop leaders and the like when many opposed it. Looks like it may be a double-edged sword for the Boy Scouts. On one hand, you have troop leaders who are gay and actually using it for praying on innocent kids and on the other hand you have parents who, because of these very decisions, are keeping their kids from the Scouts.
I'm not saying all Homosexuals abuse kids for there are plenty of straight folks that abuse people and kids but there was a very good reason why the scouts kept homosexuals from being leaders in the organization, even though there were many that were still in the closet, so to say, that were participating anyway it's just with politically correctness and in the name of equality or gender bias that a very select minority made changes happen that affected the great many.
At least that is what I believe has happened.
