UKIP scares the bejeesus out of the three main parties and their shills in the media because on their big single issue they better represent the opinion of the majority of the British public, as demonstrated in opinion poll after opinion poll. It's therefore necessary to denigrate them wherever possible and to portray a party which represents a wholly mainstream view of the EU as "xenophobic" if not outright "racist" in order to make it seem beyond the pale and unacceptable by association.
This media strategy is so blindingly obvious and, to judge from those same opinion polls on public attitudes towards the EU, not in the least successful.
