Oh hey ng, didn't notice you were back. Hope things are going alright.
Anyway, folks are mentioning the trans bit because it was mentioned by the cops involved (which lends it negative credibility on the face of it, but still), and is likely to cause murderous backlash even if untrue. It'd be remarkable regardless if for no other reason than how rare it is -- the huge majority of mass shooters are very much not transfolk, even with a steadily escalating genocide campaign being ginned up against them.
It absolutely is correct the shooting itself is more important, though. I just think most of us are pretty resigned to exactly fuckall being done on that front. One wing of our political landscape doesn't have the power to force much through, and the other wing is, well, trying to legalize open carry in florida and whatnot.
What it will take for things to change when it comes to gun control and the mitigation of events like this is for american conservatism to be broken as a political movement. Until the GOP and their ilk can no longer prevent positive change on that front, it will not happen, and the regularity of the incidences in question will largely either not budge or escalate. There's not really anything else sufficient to make the problem budge.
