Re: "This case entirely distorts" . .
I'd probably describe my political position as slightly left of centre, but the Overton Window has moved so far to the right over the last few decades, that sensible centre-left policies look like communism to these people. I'm not even a member of a union (although I probably should be, and so should you).
If you think about the actual "radical leftism" this country has had in the last century, it would pretty much describe the formation of the NHS and social security. Many of the rights and privileges we enjoy as citizens come from the actions of the radical left, but thankfully well before our time. Things like weekends, the right to a safe working environment, maternity leave and pay, that sort of thing.
Quite frankly, I think we should all be a bit more thankful for the things the radical left have done for us, and appreciate that politics is a constant struggle against the creep towards the right, which, if unopposed, will end up with a tiny number of people owning everything, and everyone else being indentured to them and living in poverty. You know, like the liberal economics of the nineteenth century.
