I don’t know. It kinda works when you finish with “I don’t think leftists should be allowed access to firearms.”
My old uncle Ed was sort of a cattleman range warden, and he told me once that you should only own what you can carry, and carry it always. He owned a hogleg pistol, and a shotgun and a lever action, and were always with him - were never left in the house under lock and key or where ever. He took them to work on up his horse and/or ATV and/or snowmobile and used them everywhere, and quite often.
I always thought that was kind of an interesting Concept and made for a interesting mental exercise, however the what ifs involved are for people who have many multiple guns and no workable solution would be Physically possible. the end result being Twilight Zone scenario where the man who only likes to read has his glasses broken during a nuclear disaster and finds himself on able to read the multitude of books at the now wide open and wrecked Library.
If I was able to only own what I could carry into carry it always it would probably be a pistol and AR-15 with a grenade launcher under the barrel. But practically speaking, a pistol. (Remember, this is a mental exercise).
If we could only own but we could carry and carry it always the end result would be no loose Firearms laying around for kids to get into trouble with.
A workable solution to this mental exercise, and for those who hunt Etc... and cannot possibly carry everything with them all the time... the need will exist for businesses who would rent the Firearms as needed for the game hunted. But - they can always carry their Firearm of choice.
I believe the 4473 says you cannot possess a firearm if adjudicated mentally ill by a court. Since leftism/Marxism is a mental illness...
