Gwen, on reflection I accept the manner in which I attempted to air the issue of Offliner's nationalistic outlook on the article talkpage after Offliner proceeded to strip all non-Russian viewpoints from the article lead was somewhat brusque and could be construed as a personal attack, and will certainly be more careful in my choice of words in future. 
I'm not alone believing this was not a case of outing, and making unproven allegations of misconduct, in this case outing, is also a form of personal attack designed to undermine the other editor, and Offliner has been warned in the past not to file such vexatious claims. Offliner is a veteran of filing complaints on WP:AE, and if this comes under WP:DIGWUREN (and Kuril Islands dispute seems to fall outside of the scope of that case being Eastern Europe), he should know that board would have been the more appropriate place to lodge that complaint, but perhaps he wouldn't have achieved the same result. This whole incident illustrates the dangers of taking complaints at face value and taking action before adequately investigating the issues or allowing discussion of the incident to mature.
