I think that has died down after the agreement (where they agree not to claim that any more). Their claim to ancient Greek heritage was an overreaction to a Greek overreaction to drive them out of south Macedonia (the Greek part) around 100 years ago. Before then, both races were coexisting pretty happily, as far as I know, but the Greek government decided to launch a propaganda against North Macedonians (slavs) in the early 1900s. There is some reaction within Greece after the agreement, about how it's a betrayal etc, but I expect that to die down pretty quickly now that the matter is settled.
