Ethno-Nationalism is a term coined by BNP leader Nick Griffin to dress up his racist policies so they will be more appealing to a larger electoral population of idiots who think "Ooh, ethno-nationalism, sounds interesting! I'll vote BNP and think about what that actually means later." Hence it is perfectly possible to encounter a Sikh SNP politician in Scotland, but all BNP politicians claim descent from illegal immigrants who came to England with William the Conqueror, Hengist and Horsa or in Viking longboats.
