the truth is that despite what the media might lead you to believe, 99.999999999% of people do not want to cause senseless destruction of society. in fact they rather like how functional society is. it's why every electrical grid on the planet has basically no security despite being so fragile that a squirrel can blackout multiple states for days by chewing a random wire. and nobody bothers to actually go after electrical substations. the only reason they even have fences is to gently guide fentanyl zombies around them for the zombies' own safety. even notable attacks, like calling in bomb threats to the bridges to manhattan to block traffic don't inspire copycats despite being trivially easy to pull off. there are hundreds of large public gatherings every single day, and nothing happens almost 100% of the time. even truck of peace attacks are vanishingly rare. the only reason they're scary at all is because of media overhype and the inability to foresee when one of these rare attacks will happen and the inability to reasonably defend against them. diversity bollards, though mocked, are honestly enough to prevent them.
