How is mine POV? If I have to re-post every "authoritarian" sources in each section than I will do so:
The following are style guides for popular publications on how to properly address the country:

And finally this is how the Government refers to itself in English:

I don't know what other "authoritarian" sources would convince everyone what the proper usage would be, but let me know and I will go and find it.  Otherwise please refrain from using the defense "There is no higher source I won't accept" or the even more ridiculous "I should be able to call it what I feel like".
Also it would need to be shown that virtually all relevant authorities on English usage agreed on this point (which I very much doubt) which I challenge you to prove otherwise!
