Shouldn all American gun owners unite behind one organization?
Yes. Gun owners should unite behind one group, if that organization agrees with gun owners. If you have joined with the NRA to “unite” you are then a de facto supporter of gun owners registration (the Brady bill), the Lautenburg gun ban (domestic abuse ban), concealed registration (restrictions and tracking of concealed carry permit holders) and numerous other gun controls. Uniting behind an organization that supports as many — albeit slightly less onerous — gun controls as it opposes might “unite” the gun movement, but in the opposite direction desired.
