Our parish doesn’t do anything with the girl scouts for this reason. Parents have asked, and it’s a good opportunity to inform them.
For a long time, Catholics were not allowed to participate in regular scouting because it was perceived as a very Protestant organization that did not regard Catholics as Christians and also, iirc, that it placed loyalty to secular authorities too much to the fore. There were separate Catholic scouting type groups. This changed after Vatican II.
Guess it is time to review this again. Actually, past time...the Girl Scouts have been little handmaids of the state, particularly with regards to sexual morality, for years now.
