Sadly, the 2nd Amendment in its current incarnation is subversive and repealing it may be needed; this should be future legislation on gun-ownership in America, as well as Western Europe
1. Membership in a right-wing, nationalist party should be required for gun ownership; this would help prevent subversives and degenerates from owning guns.
2. Women should not be allowed to own guns unless they can prove it is necessary for self-defense; such a thing helps subvert man's natural dominance over them. Only one who is physically fit enough to serve in combat (which 99% of women aren't) should be allowed to own a gun without severe restrictions (ideally, all public and private schools will be converted into military academies with mandatory right-wing nationalist curriculum, so all males with membership in the majority or national party who pass fitness standards would, be ideally able to own them upon graduation).
3. Minorities with high rates of crime should be profiled by the state and disallowed to own guns; or at very least, profiled stricter; as this allows potentially dangerous minority elements to subvert their natural rulers.

This would, of course be a much better right-wing nationalist platform to run on; the 2nd Amendment in its current state is archaic and subversive and should no longer be used and abused to grant subversive "rights" to people, or potentially empower the degenerate, the immoral, the underclass, the values of radical feminism - against their enlightened and natural rulers.
