Yes, they were born in what was then Poland, but the majority of population in Eastern Poland was Ukrainian. Varsovian is trying to add the category Polish Nazi Collaborators to the articles and none of his sources states that. And seems that instead of using the article's talk page to discuss things, he immediately ran here, working hard to make Sandstein declare it's all "bickering" and set another of Varsovian's beloved interaction bans. Instead I think we are rapidly approaching the point where a topic ban for Varsovian from all Polish articles for 6 months is in order.
