Gun owners know that it's a step process, eliminate 1 category of guns, then a few years later go back and eliminate another category until some point in the future where all rights are gone, its the long game of the anti gun advocates that have gun owners concered. Unfortunately, even though it may be reasonable to eliminate certain categories of guns, or make certain guns more difficult to possess, because that will be the first step of a continued assault on the 2nd amendment those actions are opposed vehemently every time. Unfortunately there are many people who believe the population should have no guns and no rights to defend themselves, the far right and far left not reaching a middle ground always causes issues.
