In Greece we have Golden Dawn that behave much like Kach. They go around terrorizing minorities and even threaten other Greeks. They oppose democracy in Greece even in sense of only Greeks democratically deciding our laws (as opposed to the Christian Bible or Golden Dawn). They rant about Turks, Jews, Muslims, Slavs, and so on. Not in the sense of national conflict against threats to Greece but in the sense they treat other groups as subhuman.
In the sense that I want to keep Greece Greek I am on the same page as them but their definition of Hellenism and methods are morally untenable. Not every action in defense of the nation is justified. There are ethical red lines and they cross them over and over again. The goal is not to dehumanize all others, A definition of Hellenism that requires that would be not worth preserving.
