To those on the left, that IS a right-wing fruitcake! Everyone who disagrees with them in any way is a right-wing fruitcake.
Mildly patriotic? You're a right-wing nutcase.
Don't hate your own country? You're a right-wing nutcase.
Don't believe we should be re-writing classic novels? You're a right-wing nutcase.
Don't believe every migrant is a genuine refugee? You're a right-wing nutcase. Don't believe that everyone on disability benefits is genuinely ill? You're a right-wing nutcase.
Never underestimate how full of spite and hatred the left really are. They hide behind a mask of moral superiority, but when you get to know them, you often find bitterness, cruelty and breathtaking intolerance. They hate ordinary, suburban, Daily Mail readers like your mum. For example, I knew a local conservative counsellor, a very nice, polite, middle-class lady who lived in a detached house on the edge of our village. An estate was built next to her, and a 'problem family' moved into the social housing bit. When she complained about their behaviour, they made her life a misery. When a left-wing neighbour of mine heard about this, she literally burst out laughing. She could hardly contain her joy at the thought of "that posh b*tch" having her life ruined. That's the left in a nutshell.
