Hey! Glad to see you're okay. As for proof that people have been defining 'vestigial' with still being able to have some functions (that could have been worded better) since the theory  began, take a look at the sources I added to the Vestigial structures article. Darwin, Weismann and Wiedersheim (who is credited with coining the term 'vestigial' to refer to them) all used it in this way right from the beginning, in the 19th century. So it isn't a redefinition of the term to match a discovery of function, it has always meant this. Hope this helps, but I suspect you will still disagree.
