I agree 
It seems a one dimensional view of America and Americans. The debate here is just as vigorous between Americans, Kara et al. might be surprised 
I am an anomaly in this debate, by the way (in that I am for consistently enforce, regulated sale and possession laws). If I had to guess, Warlock represents a more typical proponent, knowing very little about his views other than what I see in this thread, that's only a guess.
I wouldn't say I represent a typical proponent. I'm in complete agreement on better registration for new and used firearms, renewable licensing for firearms as well as ammo, I'm all for the idea of building a rifling database to track spent rounds.
The "A Typical" Pro Gun advocate could simply be viewed with the typical phrase "You'll take my guns when you pry them from my cold dead fingers!"
I'm simply against an outright ban of firearms. Banning ammo would only boost sales of ammo making equipment.
It's really rather simple to make your own ammo, even

of modern ammo. I used to target shoot civil war era replicas. I have a custom CS Richmond Carbine and Musket, making 500 rounds ea takes me about 2 hours, which really is mostly time for the lead to melt on a single burner and then time to cool enough to wax the base of the round. Measuring out black powder loads takes roughly 1 hour for 1000 rounds with decent equipment.
Oh and as to the whole "No reason at all for firearms" debates:
Many carry a rifle or pistol when out in the wilderness. From farmers checking on land, to hikers, surveyors, etc. They most carry at least something to protect themselves for wildlife. A rabid dog isn't something you can converse with and talk out of attacking you
Hunting. Not always a matter of sport. Many still hunt for food. While not a need for food, there are many people that enjoy such food, some whom it is a way of life. Plus thinning out populations. As we build more and more urban areas, the animal population gets more and more compacted into smaller areas. Its much kinder to shoot an animal with a firearm than make it into a hood ornament.
Simplest reason: Targetting sports. It is still a hobby of many, hell it's an olympic sport.
Those are just a small toss out of rights that would be removed from law abiding citizens if firearms were banned. It's not always just a matter of crime and protection.
