Your statement is not based on the facts, SouthernComfort generally was a regular editor of the articles he changed the notation in. He can be presumed to have decided Common Era notation was better for that article and to have had at least the forbearance of the other editors. With respect to American versus British English it has always been acceptable to change to American spelling for an American subject and vice-versa.

It was NOT ok. SouthernComfort's sole edits were to change the date formats. This would be the same as an editor changing all American spellings to English spellings and getting away with it because they are offended by American spellings.
