Koala claims that there are no legitimate descendants of the Hohenstaufen, which is a different thing than saying that legitimate male line is extinct. And in this very case, it is incorrect to allege that legitimate descents via women are nonexistent, while legitimate male line descent truly is extinct. They are not the same thing, as those of us who know genealogy, are well aware. I observe that the Yopie has chosen to join the same falsehood. I think Yopie and Koala need to cease their falsehoods and stop those edits of theirs. I understand Yopie is not fluent enough in English (being obviously a foreigner, from Czechia). Those 'warnings' Yopie distributes here and there, are manifestly unwarranted, and rather a signal of twisted tactics in Wikipedia conduct than anything constructive. For example, Yopie sometimes alleges vandalism in clear cases of non-vandalism. Yopie's such behavior should and may lead to him getting sanctioned.   

as to Yopie's quibbling using unrelated claims, I suppose he means to say that all female-line descents from all dukes of Anjou are illegitimate. But of course those who know genealogy and titles, are aware that strictly speaking, neither of those peinces actually are 'princes' of Anjou, they would themselves be first to admit that their claim is to the title of duke of that. While Louis' daughter may well be known as princess of Anjou, if they so wish.
