Boy Scouts is about surviving in the wilderness and not getting lost. Being prepared through knowledge and training to face whatever emergency arises. A scout is trustworthy, loyal, helpful, friendly, courteous, kind, obedient, cheerful, thrifty, brave, clean, and reverent, remember? Don't see tolerant on the list, but it might be implied.
A Scout is FRIENDLY.... He seeks to understand others. He respects those with ideas and customs different than his own.
A Scout is REVERENT. ...He respects the beliefs of others.
So the word "tolerant" isn't present, but I believe the concept is.
