The only way forward I think, if they want it, is to actually put gun safety and political instability back into focus, and figure out a way to indirectly imply Trump's rhetoric created a country where such an event was possible. That would mean not letting up in campaigning on the fact he'll be a dictator, and directly saying that he's now a dictator out for revenge once he gets into office, and that we shouldn't have to pay for something someone in his own party did.

Now, this will be hyper inflammatory to the Trump chuds to be sure, but when they tell a normie such direct arguments, the normie might nod along but deep down will not see anything wrong with it, making the outrage contained to inside of the conservative sphere. Basically, the only way out is through, the only way out is for Democrats to once in their lives not lighten or temper their rhetoric just because the right hysterically tries to shame you into doing so, forcing them to hit their ceiling of anger with no hedging on your end and waiting out their bluff.
