the only beneficent quality of republicans is supporting the NRA,
Look, I like guns far, far more than most people, but I draw the line at the NRA, and Wayne LaPierre's suit-fetish. Most people that work on 2A issues at a local level will tell you that the NRA will swoop in after a deal has already been made, and fuck everything up. If you look at the history of Heller v. D.C., you'll find that the NRA tried to kill the suit before it even got off the ground, because they were afraid it would hurt their funding.
If you want to support 2A causes, the Firearms Policy Coalition is on of the few right now that's both effective, and appears to avoid other 'culture wars' (e.g., "anti-wokeism") nonsense. At a non-policy level, the various John Brown Gun Clubs are doing good work, the Liberal Gun Club is helping create a space for people that are both pro-gun and generally identify as left of center, and the SRA is pretty okay once you get past the tankies.
