'Ancient' Celtic identity

[smmg]

I think it's weird how people seem to assume that the Celtic nations have always had some sort of ancient, unbroken "Celtic identity" that stretches back thousands of years, and that we've always had some sort of sense of "Celtic connection" between us that is similarly ancient and unbroken. When, to our best knowledge, no one from the modern Celtic nations was describing themselves or their languages as "Celtic" until George Buchanan in the 1500s and Edward Lhuyd in the 1700s, and that the relationship between the Brythonic languages, Gaelic languages, and older continental Celtic languages wasn't recognised or labelled as "Celtic" until then either. It is, at best, strange and historically inaccurate when people act like our cultures have always had some sort of strong, unbroken, ancient Celtic identity, and at worst it romanticises our cultures by painting them as ultra conservative, traditional, ancient, and somehow more inherently in-touch with our past. And potentially has weird white supremacist connotations with the fixation on the "ancient"/"traditional" aspects of it all and the emphasis on our "ancient heritage"/"ancient identity".
