Character had nothing to do with that.
Troop leaders are unpaid volunteers and when they have all the girls they feel they can can handle (5-10-20 or 30) they do not have to accept any more girls into their troop.
Anyone who has tried to manage 22 1-3rd graders after school, with only an occasional parent helper, like I did, understands this.
That is when a parent who is told the troop is full, has to step up and start a new troop.
And THAT is character.
As for character, it used to be considered a qualification for scouting. Nowadays it wouldn't surprise me if being a girl isn't necessary. In any case, the girl I referred to would have been a splendid addition to the troop, and that is all.
As for "when a parent who is told the troop is full, has to step up and start a new troop...THAT is character;" surely you realize not every parent is able to do that, and being unable does not reflect on their character.
