Good point. I am sure we have some here as well, but from what I saw the east coast is stocked with them. Quite the times we are living in.
I suppose you guys already practice this but taking these people to the range is really worth the effort. When they find they can't hit diddly with a semiauto anything they stop worrying about the capacity issues. Of course handing a total novice (or worse an out-and-out gun phobe) a semiauto pistol is a bit dangerous so you gotta watch what you are doing and maybe start with single fire, But in the end, give them 4-5 targets and let them see how hard it is to hit them shooting "as fast as you can squeeze the trigger" is pretty enlightening for them.
I have four of them now gun owners and weekly trap shooting partners in the summer time.
Only way I know how to deal with these folks and make progress.
