You if you think that shows prejudice consider Greeks that just opposed use of a name not state recognition. Pretty much everyone knows our Slavic neighbors aren’t “ethnic” Macedonians anymore than Hamas are “ethnic” Macabees. And many many nations ignored our concern for even just that. Today there are around -5-6 billion people playing dumb as our former Yugoslavian neighbours now claim not to be Slavs but antihellenic founders of the Hellenistic period.
