Some gunsmiths / custom gun builders could be called "obsessed" as they strive to make a perfect form of art, that just happens to be called a firearm.
However, they are no more "out of it - obsessed" than an artist whose canvas is actually canvas and paint, or clay pottery etc.
I finish my own stocks on slightly higher end single shot rifles and refinish / restore old shotguns. Could I be called obsessed ? Maybe as I try to get them "just right", but I showed the same care and concern for the companies I worked for when I wrote computer code for a living.
I also showed the same obsession when I was younger and did tool and die work and high precision machining. That same "obsession" to do things right helped keep all of you safe when I was involved in Reagan's military build up and I hard to work out the machining problems on some very critical intermediate range nuclear missile guidance systems.
That doesn't make me a problem child though.
People that enjoy the shooting sports and are passionate about their hobby are no more "obsessed" with it than say Tiger Woods or anyone else that strives to do their best in golf, or bowling or any other non-couch-potato activity that requires "equipment".
Only nut-cases are "obsessed" in the connotation that the leftists are trying to convey about gun owners, leaving out the golfers etc.
They also confuse the resolution to defend oneself (instead of relying on "the authorities" to do so) with "obsession".
Also the appreciation of the "art form" of the firearm is being confused with "obsession". If a person is passionate about collecting Ming Dynasty vases, or prints from artist Sarah Richards (who does wonderful watercolor prints of horses, we have nbr'ed prints, the originals are pricey) they are not classified as "obsessed" in the way that firearm owners are being tried to be classified as.
