I refer to your message. 

 Since you are a Portuguese masquerading under an Icelandic identity, your accusation of "vandalism" rings distinctly hollow.  It is not I who is seeking to undermine the integrity of English Wikipedia, but you. 

 As you well know: 

 (1) This is an article about the Autonomous Community of Galicia, a political entity within Spain. 

 (2) The official name of this entity in BOTH Spanish AND Galician is "Galicia", not "Galiza".  As the text further down makes clear, the term "Galiza" (identical to the name of the region in Portuguese) is championed by sectors of Galician nationalism who abhor anything or any term which smacks of "Spanishness". 

 (3) The version of the article you are seeking to peddle is misleading by virtue of giving the impression that the spelling "Galiza" enjoys some sort of co-official status with "Galicia".  It does not. 

 I do not know whether you are simply ignorant of the true position, or disingenuously giving vent to some anti-Spanish cum Galician nationalist agenda of your own.  Either way, please do not insult my intelligence (or that of other English Wikipedia) users by posing as a disinterested or impartial adjudicator on this issue.
