That's some heavy historical revisionism right there. The self proclaimed King of Greeks, with a Greek name, who spoke a Greek dialect, believed in the Greek pantheon, and won 3 times in the Olympic games (which were infamously for Greeks only!) was not Greek?

Greece as an ethnic state is a modern concept, if you say "the Greeks hated Philip" to refer to Athens and other city states who were in conflict with Macedon, then you're using the Greek label erroneously. The Greeks were not a single peoples but a somewhat culturally, linguistically and religiously homogenous group of clans and the states they formed through the years.
