Can you point to any that have guns as accessible in the US that don’t?

Well seeing as there are none that are exactly the same I suppose you’ve set yourself up for an answer you want, but I’d be remiss if I didn’t mention that the Czech Republic, while they have a slightly different system and less guns to people ratio, they’ve had the right to firearms enshrined like America since the 1500s (except during nazi and communist occupations where they were outright banned and restricted to those deemed loyal respectively). Not only that, but in CZ just as US, though gun ownership grows, gun crime declines.

Furthermore, there are plenty places in the world where guns are completely banned, yet the criminals have them and use them regularly, like Honduras or Brazil. The problem though is you’ll discount those places as brown people third world countries so of course those savages poor browns “unfortunate souls” kill each other a lot (which isn’t racist at all somehow). Point still stands however, even illegal guns shipped to an island aren’t prohibitively expensive to actual drug dealers, even without guns being legally available, people are making 1911s in the jungles in the Philippines with hand tools out of scrap steel that run just as well as a Springfield, the cartels get full auto M4s and South Korean grenades, those are illegal here much less Mexico and they still get them.

A knife is not nearly as deadly as a gun. You can at least run from a knife

Ahh ableism! So fuck cripples who can’t run, huh? And the old who are slower than most people victimizing others with a knife? And fat people? Might as well let him carve a few pounds off hmm? Or even women, since men run faster over short distances on average? Hope your last name is “Bolt.”

Y’know what ends a knife fight quicker than running and prayer? Well, one time a dude pulled a knife on me and my then GF walking into walmart, before he could say anything I grabbed the grip of my CCW but didn’t even draw it, he turned and walked away for some reason, couldn’t say why but I have my theories. Must’ve been less than 10sec but felt like an hour, still though, nobody was hurt and I’m fine with that.

its much more personal so less people are willing to use it,

In theory, but in practice they’re used to threaten and attack people regularly already even with legal gun ownership. They’re cheap and actually accessible (there’s no FBI NICs check or prohibited purchasers/possesors for knives). Btw you can run from a gun too, once you get 25yd away most people (especially criminals who aren’t known to train or practice) will not hit you with a handgun, which are involved in the most crime (12,000 handgun to 500 rifle deaths a year, criminals like handguns for concealability.)

Public transport

Well no, that Bastille Day incident I mentioned happened with a stolen truck “lorry.” “Lorries” will still exist for shipping purposes. Furthermore bus drivers can also kill people, they aren’t some saint just because they’re employed by the city, they’re drug tested 1x/yr for their CDL but that’s about it, and busses can also be stolen. Though yeah, public transport could surely be improved I do agree lol.

Mustard gas

Interesting you note this one, do you also think precursors to make mustard gas should be illegal since it’s so easy to make? I mean, you support banning guns because they can be used illegally, or at least making them harder to get, why not ban/restrict the ingredients for mustard gas the same way? They’re legal now, just like guns, you’re just not allowed to kill people with it, just like guns. Maybe the issue isn’t actually the implement used to do the killing, maybe the issue is the killing itself.
