lots of the same issues that these sports had. When my son was in scouts, it had totally changed. There was adult education on child protection that had to be done every 2 years, rules about having to have at least 2 adults at any meeting and an adult could not be alone with a child that wasn't theirs.
Scouts live with their parents too, it's not about living with their parents or not, it's that parents have to be involved.
If this didn't change, there would be no scouts. I don't see this changing in gymnastics, ice skating, etc.
