Ah, but is there relevance? If Sumple still supports his previous views, then there can be no defamation (no doubt he'll be proud to have a wider airing of his opinions), and if he doesn't, then he only has to retract in order to rectify the damage that his publically-stated views have caused. I for one am very offended. I feel it my duty to bring to the attention of the entire Wikipedian community the potential bias that might be introduced into edited articles. He only has to retract for us all to breathe a little easier.
