It's a stupid article, but then again the author's probably only familiar with the last 5 years of furry at the most and has a deadline to meet at his unpaid internship. The 1999-era "nazifurs" from that LJ he mentioned really *were* uniform fetishists and shock artists, and were only interested in the iconography to get off and/or look ridiculous. The exceptions, if there were any, numbered in the single digits.
Then around 2004, the ironic racism game started in full with 4chan and you got people getting into it uh, a little too deep.
It got worse from there. Half a decade later the bottom fell out on society, politics got ran through the blender, and you really did start seeing weird ideological chimeras like this begin to emerge. Remember Weev, and how just a few short years on the inside made him emerge as a fascist figure to rival David Duke?
Furry's had impossible-seeming right-wing weirdos as part of the community since the very beginning. They're just getting worse, along with everything else. They likely see themselves as emerging at the top of whatever crazy racially pure society they want to create, and thus not subject to it's rules. All forms of identity/ethnicity/etc are 100000% compatible with reactionary thinking. The mental gymnastics involved aren't as strenuous as you might think.
