What kind of UK do BNP supporters live in?

Living in an area full of immigrants and having/seeing no problems with it whatsoever, I've started to wonder whether nationalists are actually living in the same country as me, or indeed the same planet for that matter. Nationalists do sometimes have me believe they are some kind of alien experiment gone wrong, unless the intention of it was to create the most ignorant people in history, that would be a success.
