Noah, I'm sure that you realize that the edit you are proposing is controversial, regardless of what source you are using. Given that the source is from the website of a Canadian freelance writer and Albanian language linguist (rather than historian) not affiliated with any university who's published works mainly related to Albanian literature I would say that he is not a good source on Albanian/Kosovar history. As for the edit as such, using terms like "final solution" are not NPOV. I suggest that you find additional sources and rewrite the text and post for discussion/comments on the Talk page.
