I have a weird comment, but i felt less confused about the world when we rumors came out that the shooter is in a relationship with someone gender fluid or trans. The idea of him shooting Kirk cuz Kirk wasn't conservative enough (and importantly that some groyper discords drove him to this act) was too much for my brain to fathom. It sucks that MAGA will assume the trans partner along with his one semester at a University poisoned him, but it make more sense to my peon brain.
EDIT to add - i know we still don't know the motive, but I assume he felt he was defending against attacks on his parter, again, largely because that's something my little brain can fathom.
