An anonymous editor is edit-warring in an attempt to replace the term "Republic of Ireland" with "Ireland".  There are two reasons, however, that the latter term is appropriate: 
 # To avoid confusion, since "Ireland" is also the name of the island; and 
 # The name of the football jurisdiction in any case is Republic of Ireland. 
 In the interests of clarity and to avoid confusion and ambiguity, therefore, please leave the settled text alone.    
 :That is your point of view. It is not fact. The name of the country is Ireland. Fact. To try and push some other name is wrong.   
 ::It is not my POV. It is indisputable fact that the island is called Ireland and the football jurisdiction is called Republic of Ireland.  Plus, no-one has denied that the 26-county state is officially called “Ireland”, so you are using a straw man with that one.  It makes sense to use Republic of Ireland here for the two reasons noted above, both of which I see you have elected not to address.  Your references to WP:IMOS are also disingenuous, if not self-defeating, since that policy allows for the terminology as was the case here before your intervention.
