They stopped talking about it because they couldn’t pin it on a southpaw, even though they try to do so for every single shooting, and invariably, the allegation is always laid out flat on its back by the facts.
The unfortunate thing is, that whole line of rhetoric is governed by the Principle of It Takes Only One—it this case, it takes only one legitimate case of a lefty actually perpetrating a mass shooting in the general vicinity of maga-friendly culture before Trump declares a national emergency and martial law, sending the military into every major city in the country, particularly those governed by people of color, and rounding up local political leaders, media, academia, and community organizers, as well as many of the ordinary people merely in proximity to them, by the tens or hundreds of thousands. They will be disappeared in plain sight from their family, friends, and neighbors, sequestered away indefinitely within our own country, unreachable and incommunicado, and will meet whatever their fate might be. And then we will truly be off to the races on the collapse of traditional American ideals.
