Can't agree with that approach at all. What we need is clear, transparent, consistent rules for inclusion that will be applied to all articles irrespective of whether they are massacres allegedly perpetrated by the West or anyone else. The 'case by case' approach is a recipe for WP:BIAS and contrary to achieving WP:NPOV given the numerical preponderance of British and American editors and their inevitably skewed perspective. (And while I'm here may as well mention that I disagree with your comments on the British Isles issue; "New England" is no analogy!) To ONIH I'd ask - why the hurry to get an entry into an article that really shouldn't exist at all?
