:::::No, you've pulling up op-ed pieces - and those dating back to early 2014 - not followed through via WP:RS since that time. The majority of the opinion pieces were written by essentially unknowns trying to create a journalistic profile for themselves and, in the majority, writing for the yellow press... or anyone will have them so long as the piece is attributed to that journalist (thereby avoiding any embarrassment should the article encounter any backlash for lack of cite-checking). You've also introduced WP:SYNTH where the bulk of the information surrounded interviews, some of the interviewees admitting 'sort of nazi like sympathies, but not actually Nazi sympathies') and reports from the authors that they did see Nazi tats, etc. (as noted by Mondschein English). 

 :::::My favourite pieces of bias is op-ed reporters drawing on the 'expert' Anton Shekhovtsov. No, he has made himself a high-profile 'known' by writing extremist blogs (nothing like building up an academic career by being an extremist). The only time I've seen him referenced in the sorts of op-ed articles where he is 'quoted' but never actually interviewed by the author of the article. Oh, yes, that's most definitely catering to bums on seats and establishing yourself as a well respected academic. Please note that I objected to the use of Shekhovtsov for the same reasons as not being short of a biased source, therefore inappropriate for the article's content in the Donbass general elections, 2014 here, on the talkpage. My position as to anyone using him without attribution, and only where his opinions are seen to be WP:DUE has not changed.
