Minorities and especially women should have solid access to firearms. Even 'felons' if they are historically nonviolent and have no history of serious mental illness. So many black men have been screwed with the 'felon' label for nonviolent drug offenses since the bogus drug war began that it's economic and cultural genocide. Take all of those people, strip their voting rights, rip their families apart, and their communities suffer from even greater abuse by police abuses in that fundamentally racist policy.
The media is also complicit in skewing the reality our country faces in regards to firearms and danger. Despite the news coverage focusing on flashier events, actual statistics show that the vast VAST majority of firearms murders are single perp, single victim, using a pistol. Further, this is dramatically more common in economically disadvantaged areas, not coincidentally areas where terrible institutional racism and the drug war have combined to create an environment rife with completely rational fear of the police as well as few opportunities to earn reasonable income legally.
Ending the drug war, and refocusing those resources towards improving life for the most socioeconomically disadvantaged areas of our country would be the single most effective way of reducing gun murders in terms of saving lives.
In the meantime, AR ban or no ban, 10 round mag or 30 round mag, these things would not amount to very much in the big picture. The more effective options would be increasing waiting periods for males under 25 years old, and comprehensive mental health checks (outright ban on anyone with even misdemeanor violent conviction, schizophrenia, BPD, etc). Mandatory smart safe for home/business, tax incentives for providing smart user recognition for taking off safety.
A happier, less racist, more equitable society is less violent.
