I don't think the style of multiple revisions to walk back the most problematic parts really helps the case. It very much leaves me with the impression that the original version is the one that the author really meant, with the revisions being just a weak attempt to deflect criticism.
So if you leave a post unchanged, it's proof you meant what you wrote; and if you edit it, it's even stronger proof you meant what you wrote, even if the edits signify some change.
I understand that many interpretations are open in such things, but this kind of logic seems ridiculous.
