When someone's first instinct is the logical fallacy of Appealing to/from Authority you can almost be assured that they don't have the actual facts or knowledge to back up what they're saying. If they did, then they'd just present that knowledge.
From a cursory look at Arizona's requirements for a Non-resident permit, you don't even need to shoot.
"...4. Completion of any national rifle association firearms safety or training course..."
You could take the NRA Home Firearm Safety Course, which is described as a "Non-shooting course and teaches students the basic knowledge, skills, and to explain the attitude necessary for the safe handling and storage of firearms and ammunition in the home."
Heck you could go with paragraph 3. "Completion of any hunter education or hunter safety course approved by the Arizona game and fish department or a similar agency of another state."
What are the Pennsylvania requirements for a hunter safety course?
