Most people don't understand the difference. And to be quite frank, the organizations running the polls might not understand either, or it's in their best interest to not explain

I thought you were maybe speaking more expansively though. Like what about people that think almost no one should privately own a pistol or whatever.
(ie. recheck any odd notions you might have about gun bans in Australia)
Stricter gun laws, more complicated laws aren't the answer - simple clear uniform gun laws, equally reinforced will do the job.
Unfortuneately the very nature of the (un)United States seems predestined to never enact uniform laws wrt firearms let alone maintain an up to date central register of information etc.
