The Greek embrace of Alexander the Great and Macedonia is amusing, when one remembers how violently the Greeks of his day resented him, and how barbarous some of them said the Macedonians were.
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.
