But from "Sargon's" perspective, UKIP isn't fascist - it's the party attempting to remove the UK from the growing, minimally accountable supreme bureaucracy known as the EU.

It's always better to understand your enemies before you start to insult them. Otherwise your insults just increase polarization, because while people who agree with you will find them obviously true... People on the other side will find them objectively false. And we don't need more polarization nowadays.

> inherent beliefs of racial superiority

IMO painting all belief in racial differences as racist/fascist (which is what this tends to devolve into) is a great way to ignore actual problems. Problems like medicines being tested on populations of primarily white men and women not always working for african americans or other groups... And of course this is an area where one side is politically correct (no differences below the skin) and another is factually correct (different ethnic groups have significant differences in susceptibility to disease, athletic performance, etc).
