That I can’t vote Labour or Lib Dem because if this is THEIR fault, not mine
You're right, it is, but that's not the way some manic activists and the sort of metropolitan chatterati Fireflygal mentioned will see it
To some of these it's all your fault because you refuse to see the absolute rightness of their views, probably with something about being "brainwashed by the media" chucked in.
It's almost as if they resent people being able to think for themselves and coming to a conclusion which differs from theirs, and so they continue to strike fashionable positions, ignore the vast swathes of moderate folk who want nothing to do with silly ideas, and then act surprised when the next electoral loss rolls into view
Shame, really, because the whole thing is leaving more and more of us politically homeless
