 == SACN == 

 You seem to think the English accronym is CSN, when it is SACN (South American Community of Nations). Either that or you are an idiot. Either way, the English accronym is SACN and therefore the one in parentheses, and the preferred ""CSN"" usage should be explained afterwards (which I did, no thanks to you). I would advise you against lazy and hateful reverts, they do no good.  "
