All the photos that have come from this shooter (the guns, the notebooks) seem to point like he was desperate for online attention and to go viral on 4chin. This makes me think he specifically LARPed as a tranny ahead of time so he would get more attention on 4chin when he did it, because a tranny shooter would obviously go more viral than a regular one, due to the existing meme/fact of (actual) tranny mass shooters
