Medical treatment, an allegory...
Doctor: "the test results are back, I'm afraid your child has cancer"
Parent: "OMG. Is it treatable."
Doctor: "yes... But we don't do that."
Parent: "what do you mean? Is the treatment awful, or ineffective?"
Doctor: "... No..."
Yes, look: these horrible people spent most of the last two decades deliberately rehabilitating as much of the National Front’s politics as possible, while telling audiences that anyone resisting them was a traitor plotting to destroy Britain. *Of course* they are going to stick to that now.
