Race not being well defined is part of why this discussion is fraught.
If you were to ask Winston Churchill about race he’d define it as something closer to what most people now would call nationality (e.g. he’d say that the Boers were a different race than the English even the ones who’d long lived in South Africa). An Idaho white nationalist on the other hand hyper focuses on skin color (with perhaps some religion thrown in if they are a traditionalist).
