I'm going to tell my spouse that girls belong in the GIRL Scouts and boys belong in the BOY Scouts
Why not just combine them to make them scouts?
This is how things were when I was a kid.
If that is what you truly believe, then you have the right to feel that way. It is okay to stand up what you believe in.
I'm done with the Scouts and I won't let my kids take part in them. They are so evil.
I hope you will be able to start your own organization with parents who can see the merits of allowing genders to work with each other exclusively because it's good when everyone can share the same vision.
