:If there is a verifiable quote from JKR establishing parallels between Death Eaters and the KKK specifically (as opposed to generically), then it belongs on the page on Death Eaters, not Voldemort. The similarity between "Voldemort" and "Völkermord" is hardly significant (more like "coincidental", especially given the very different pronounciations of the german word and the way JKR established Voldemort should be pronounced), so absent some indication that it played a role in the name, which again comes down to verifiable, reliable, citations, it is nothing but wild speculation, based on coincidence. I am sure we could find all sorts of correlations with other words if we search through the hundreds of languages and dialects that exist, with all kinds of characters in the series. It is not notable, and it is original research. Write a paper about it, get it published in a reputable literary analysis journal, get some discussion going among reputable researchers, and then you can source it and add it to the page. Until then, it belongs in a fan forum, not here.
