Depends on what your definition of average is

So Chuck the Schmuck has claimed that the NRA is a "Fringe Group" and doesn't represent the average American Gun Owner. 

So in looking up the word "average" I found the following;

Adjective

Constituting the result obtained by adding together several quantities and then dividing this total by the number of quantities.

I guess if you only represent the James Yeagers, Alex Jones' and their nut huggers, then yeah, 'average' isn't.

But when the NRA adds 250,000 new members, really how many of those folks are what Chuck the Schmuck considers average?
