Hey there! I don't want to have an edit war right now, but TV Series antagonists that are deceased were recently changed from "serves" to "served", so I thought I'd do the same with Fear antagonists (and I'm not even the one that started it). If you think they should stay the way they are, please explain why.
Since you flippantly continued edit-warring with no further words and did not contact me on my talk page, I'll just do it instead.
The standard American ethnic terminology system applies only to Americans; this is to specify someone's ethnicity while simultaneously denoting them as American citizens, hence: "African-American", "German-American", or, more vague: "Caucasian-American".
As Clara is an Irish national and ethnic, and most likely not an American citizen, she is only referred to as Irish, as the Irish, as an ethnicity, are "Caucasian" and thus do not need to be referred to as anything other than Irish.
Let's play devil's advocate and say she is not ethnically Irish, but for example, Scottish. Would she be called "Scottish-Irish"? No, she would be called "Scottish-born Irish" or "Scot living in Ireland", as Ireland does not use the same terminology as the United States, and the United States doesn't use that terminology for non-Americans either.
Accusing me of being a troll was not necessary at all. Try to be calmer when editing on a wiki in the future. Also, do not edit-war. This is what talk pages are for.
