As a society, or just an aviation interest group, we cannot survive by passively accepting or teaching to the lowest common denominator. Some people, and frankly I just don't care enough about the Grumman "driver" to deduce where he lies on the scale, shouldn't operate aircraft, boats, or wheeled vehicles; shouldn't handle secrets or other people's (maybe even thier own) money; be charged with keeping the peace; and have no business ever advising or teaching others.
Trying to make life idiot proof just means making things not work at great expense to the group. Everything has the potential for harm if used thoughtlessly (even soap).
As an example, one must always treat firearms as if they are loaded. Listening to, or worse believing idiots who believed they were not with harmful results leads to idiocy like mag safeties and loaded chamber indicators.
