Just for fun I looked at their website to see just how crackpot they were. On a scale from mildly nutty to utter fascists, these folk are utter fascists.
Normally I'd quote bits of their manifesto for a laugh, but not in this case. Needless to say they are anti-Muslim, anti-immigrant, anti-EU (not British membership of it, they are against the whole thing being in existence), anti-gay, anti-independence, anti-socialist and very, very racist. Talk of physically fighting within the UK for their "values".
