I mean, a white guy going into a village of black people and shooting up the place is just colonialist history. There’s some potential racism to unpack there, so it’s not surprising that people’s first reaction was “what the fuck.”
This was people freaking out about a white guy shooting up a bunch of other white guys who were part of a Christian extremist militia in South Dakota or something. This was people being angry that the bad guys were white Christians, a group that could never be in the wrong.
