Sorry, but UKIP are not 'far right'. They are right of centre but that does not mean fascist.
The traditionalist, ultra-nationalist, authoritarian parties have been called far-right ever since the appearance of left-right politics. It all comes from the French Revolution, when monarchist members of the various successive assemblies sat on the right while radical republicans took position on the left, and came into full swing during the Restoration when the right-wingers were sometimes "more royalist than the king".
It may not seem to make much sense today, what with the implicit redefinition of left-right as social liberalism versus liberal conservatism, but that's the actual history behind the words.
Far-right does not necessarily mean fascist, either.
By the way, I am not denying that those far-right parties have changed their electoral agenda to something more politically correct. I'm just saying that the old guard is still there behind the dynamic figureheads, and that their strategies are still hilariously recognizable. Just because we shouldn't demonize them, does not mean that we're not allowed to despise them.
