Aren't they, though? I've never met a UKIP supporter who hasn't made some comment about the "coloureds"/foreigners/gays etc. But maybe the fault lies with me & I'm tarring them all with the same brush.
What scares me is rather than stand up to them, the mainstream political parties seem to be copying them (hello, Mr Fallon).
And it seems to me, naive as I am, that it's suddenly becoming taboo in certain circles to criticise the party as being racist. Personally, I believe that fascism lite is creeping in by stealth and it's the thin end of the wedge.
Just my tuppence worth.
