Well, A) the point isn’t that, “fan service,” created this change. It’s that people’s willingness to side with outlaws over institutions is a good barometer of public anger, and based on the United Healthcare killing, people are fucking pissed. B) FDR passed banking reform and social welfare programs that created decades of economic stability and only lost their efficacy after half a century of conservative attacks chipped away at them. I’m not sure why you think a historical example of the sort of fundamental, radical change in talking about doesn’t count just because the Baby Boomers fucked it all up.
I mean, I’m sure they will, but I doubt it will make a difference. Trump almost got it twice this summer. He’s only alive because he was incredibly lucky the first time, and the second time, the shooter was incompetent. Meanwhile, in the last 25 years, schools have added metal detectors, more police, active shooter drills, and bullet-proof walls, but it’s only amounted to security theater. I’m sure there will never be another assassin who escapes and leads police on a 5-day manhunt, but there are too many guns in America to prevent a guy with a death wish from gunning down a CEO or billionaire.
