I suspect it's because when people learn who we really are, they take one of two options:

1) Realize that we're not as "extreme" as claimed, that we have some good points, and then join us 2) Realize that we're not as "extreme" as claimed, recognize that our values are not that dissimilar from normie social conservatives, and therefore recalibrate - become a far-leftist and call all right-wingers and centrists Nazi fascists who need to be deplatformed

So the only articles written about us are

1) Written by us 2) Written by raging leftists who attack all white people and conservatives as well 3) Written by people who don't know what they're talking about

Here we have option (3).

Edit: having read the piece it looks more like a (2). He thinks normie conservatives are Alt-Right...
