The guy is also shown in a photo with some “white supremacist” or “white nationalist” group, holding their “shields” with “logos” on them, and such. He did a bit more than just write a paper, it would seem...
The group that provided the shields has stated that they were handing them out to anyone and that they don’t know who he is. The image on them is a “facista” (from the Mussolini era) which seems to me a great image to use if you are expecting trouble with a group calling itself “Antifa “. Believe whatever your emotions drive you to believe. I am trying my best to sift through the BS to glean facts before the BSM can propagandize the whole thing.
