Using this logic you would tell at Scout that while in scouts do not point a gun at anyone but once you leave the meeting it is OK. This is wrong. Teaching in scouts should follow the G2SS.
While I agree completely only pointing a gun at something you intend to shoot is an universal safety rule: G2SS only applies to scouting. Some is useful in other situations some isn't.
Some examples of what is allowed in life outside of scouting:
I occasionally use lighter fluid to start charcoal fires: not allowed in G2SS.
I let my son invite people over without only one adult in the house: not allowed in G2SS.
I go hunting occasionally: not allowed in G2SS.
I follow G2SS in my scouting life because it is the rule for scouting. In other areas I follow my own judgment.
