Adamantine

[Strangerous]

Thanks Duke and James for your valuable insights. I wasn't even aware of the historical role of the censor, but am glad the metaphor survives in context. I also will definitely check out what Karl Popper had to say. And yes, even in the States, I feel the chill and am horrified by the legal developments in Britain. Finally, the idea of the title is that something immutable or adamantine might be a suitable substance for a physical benchmark subject to the ravages of a flood, and also hopefully a plausible metaphor for what I suggest is an immutable natural law holding that censorship is always self-defeating.
