I’m sure there are some elements of the “manifesto” that are trolling, but regardless, this guy was obviously a radicalized white supremacist obsessed with so-called “white genocide.” Committing mass murder in the name of that ideology is quite enough without the trolling, don’t you think?
Mainstreaming the language of the far-right nativist fringe (i.e. “invasion,” using the language of diseases and plague, suggesting that immigrants are rapists and killers) is not helping, whether that language is coming from the floor of Congress, the White House, or message board posters.
