I'm a native English speaker, and probably would have made the same mistake. 'Kick' conjugates as 'kicked', so I would have conjugated 'Kik' as 'Kiked' and 'Kikked' just looks weird to me. Though I've heard the term 'kike' before, I certainly don't hear it enough (I'm in the UK FWIW) that I would have recognised it unless it was pointed out (and obviously at that point would adjust the name). Your posts come across as ascribing malice to a fairly trivial (IMO) mistake. Politely pointing out that the name could be misinterpreted to be a derogatory term would have been a been course of action.
