"Today is not just some isolated incident. The central premise of the Biden campaign is that President Donald Trump is an authoritarian fascist who must be stopped at all costs. That rhetoric led directly to President Trump's attempted assassination." - Donald's VP pick JD Vance
That reasoning applies to insane gun laws. If you allow nearly everyone to own a gun, or 20 guns..., that will lead directly to unnecessary gun deaths. Regarding what Vance calls rhetoric, however, he is right in the same way that allowing roads and vehicles to travel on them will too inevitably lead to accidents and deaths. It doesn't follow we got to stop building roads and vehicles.
It's not just rhetoric though. The 'stopped at all costs' would be, of course. So was the bullseye comment - nobody took that as a hint from Biden to point a gun at Trump. Even if someone would, that wouldn't be on Biden, that wouldn't be a reason to stop using figure of speech. Cause that would be like ending the idea of roads and traffic cause some mentally insane drunk driver causes casualties. Like throwing the baby out with the bath water.
Aside from taking back the bullseye comment, I think Biden responded well in the NBC interview:
Pressed by Holt on whether he has used inciting language, Biden suggested that it was necessary to characterize Trump as a “threat to democracy.”
“How do you talk about the threat to democracy – which is real – when a [former] president says things like he says? Do you just not say anything – because it may incite somebody?”
I watched many many politicians (and people across all levels of society, as well as social media companies and moderators) across several nations grapple with that very key question for decades and have not seen anyone provide a winning response. They don't just not saying anything, but they have to be careful how to phrase it. Just the fact they are forced to navigate a thin line already puts them in a disposition. Cause the other side doesn't have to, they can instead simply lie and bs their way out of losing voters over it. Heck, their supporters convinced themselves it's only fair.
Worse, Vance's tweet, Johnson's veiled comments and thousands of other examples by now, paint Biden and other dems as a danger to Trump, you know, the cult leader of millions of bat shit gun owners. The GOP and Trump got themselves a new trump card, one they won't hold back.
Typical for remakes of foreign movies (it's an analogy ffs, not suggesting it's like a movie...) is that the ending is often changed to be a happy one. Usually kills the story and makes it unrealistic but Americans love a happy ending. The situation where someone who referred to the demagogue as 'America's Hitler' becomes VP is definitely a new twist that was in no original, that would be way too unrealistic for fiction.
