It is illogical horseshit, but you see it here too.That article was... ... interesting, to say the least. If these are indeed the words of the shooter, than this is indeed sad. Sad in the way that the 'manifesto' is a ham handed, ill researched thesis attempting to marry the concept of environmentalism with white supremacy using made up terminology.
Verdict: Illogical horseshit.
The kid seems a new hybrid influenced through social media extremism. He's learned a million new ways to hate. He's about the most perfect example of a magaturd one could find.
