You haven't read this thread then. I don't care if people can have guns or not, I just personally don't want/need one.
Forcing people to register firearms is a necessary step in keeping firearms out of the hands of those who society feels shouldn't have that right. Violent felonies, mental incapacity, etc. Without registration of firearms you can't prevent certain people from having firearms.
Just like seatbelt laws, many will never have had any use for wearing one. On the other hand people still die while wearing seatbelts. At the end of the day what lives are saved by seatbelts make it all worthwhile. Without requiring all automakers to include them, and then requiring any front seat occupant to wear one, those lives wouldn't have been saved. Pointing at people who still die in car accidents does nothing to change that fact.
