His manifesto is a low effort, shitty copy of Tarrants, his shooting was a low effort shitty copy of Tarrants. Either his frustrated and made a snap decision to go on this spree then wrote his manifesto; or he wrote it first and is just a literal retard.
As for glowies singling out people, do I think it happens? Sure, but I think it's avast minority of their actions. Their purpose in general is threat assessement, reduction and eventually destruction. To do the first two you need up to date models and data on what various groups do when various pressures and materials are supplied. It makes more sense from an 'individual agent time/benefit' view of things to apply pressure to groups, or form groups, then see how they act to better track how 'wild' groups behave than it does to fuck with individuals. Glowies aren't lizard men out to do devil work for fun; they're intelligence agencies that hate and want to suppress the white peoples of America. That means more than just 'lol shoot niggers', it means treating whites as potential threats; and needing constant model revisions for how groups of whites behave when facing various pressure and material.
I should clarify, I don't care that there are dead niggers, America is a nation built by whites for whites; blacks are subhuman. My consternation comes from how pointless this was; it was a pissed off man laahing out randomly without forethought, without a proper target and without any real goal. All this does is provide ammo - lol - for anti gun, anti male, anti white sentiment.
