Ec wrote There are likely some who feel offended by it, but that is the personal choice of the humourless.
It is not merely a case of having no sense of humour if you are someone of Kurdish descent and you find a contributor editing an article on the Kurds 'humously' using the name of the man who committed genocide against the Kurds. Nor is it a matter of a sense of humour if a contributor to an article on the Jewish holocaust called himself after a leading nazi, with the edit history listing a line of edits by Adolf Hitler. Or if someone as a joke decided that all their edits to articles on child sex abuse use the name of some notorious paedophile like Fr. Geoghan or Fr. Brendan Smyth.
A collegue of mine is named Moamer Qazafi -- which may not look controversial at first glance, but it is simply another way to transliterate the name of the Libyan leader Muammar Qaddafi. Would you ban him simply because his name has an unfortunate and not particularly humorous similarity to that of a tyrant?
