How about the strange death of all ideological 'isms?

They may look good on paper but they all fail in the real world. Anything practical ends up being a mixture of ideologies --- some shade of gray rather than strictly black and white.

Thou shall not kill --- except.

It seems that at the highest level libertarianism has been co-opted with might makes right sensibilities. Which unsurprisingly correlated with "libertarians" who suddenly found themselves with a lot of disposable income...

Nothing strange about it. "Liberty" is a euphemism for unaccountability, and libertarianism, probed with steel, advocates only that business must be above the law. Most predictable ever.
