It's got to be driving him absolutely nuts that the second shooter is also a presumably christian, straight, white, man. Anything else and he could work with it. White woman? Women are too emotional and shouldn't be trusted to make important decisions. Black man? Go-go all out on the racism. Brown skinned? Anti immigration fear mongering. Trans or gay? Groomer nonsense. Anything other than Christian and he could fearmonger about their foreign religions.
Literally the only identity he can't exploit is christian, straight, white men and they're the ones who keep trying to kill him.
