>America would be pretty much the same if after 1900 guns had been banned
That’s a pretty massive leap. Maybe you can ignore the 500k-3M defensive gun uses per year, maybe you can ignore the civil rights movement that was furthered by blacks arming themselves - coincidentaly this is the roots of modern gun control in the USA (a plan to keep “the wrong people” from owning guns, still rooted in racism today), ignore the “rooftop Koreans”, ignore that unlike Mexico to the tip of Chile that razor wire and bars on Windows isn’t common in USA because the penalty for property crime can be death, ignore that our military is the best in the world because of country boys that grew up with positive gun culture, ignore all you like. You’re clearly not presenting a factual argument with such a broad hypothetical.
Edit: I’ve already been sucked in to a silly line of thinking too much. The point here isn’t that you’re scared or upset about the existence of guns. It’s that we don’t get rid of things or stop people from thinking things because someone might be bad. That’s not how a free society works.
