During the aughts, I attended many of our local political parties. Socialists, Dems, GOP, Libertarians, etc.
All these cliques, for lack of a better word, are mostly defined by what they're not (in opposition to other cliques).
The exception was our local Green Party. Their members were defined affirmatively, by what they stood for, vs in opposition to some other group.
The Libertarians were especially mushy in their supposedly beliefs, and no two agreed on anything other than everyone else was wrong. Kinda like the various Christian sects.
You could add in the Mont Pelerin Society,Foundation for Economic Freedom, Atlas Network, and Cato Institute, Mercatus Center, Adam Smith Institute, Mercatus Center.
And personnel: Ludwig von Mises, Leonard Read, Murray Rothbard, Friedrich Hayek, the Kochs (Fred, Charles, David), for completeness.

See, e.g., Philip Mirowski's The Road From Mont Pelerin:

I recently read a magazine article that covers same history as Mirowski's book. Hayek's motivations and strategy for pushing his ideas (take over economics depts in higher ed) are fascinating, instructive. Sadly, I can't imagine how the left could replicate that effort for reality-based polcies.
On mobile, sorry no link handy. I'll edit if I can find it.

I'm not immediately recalling or coming up with a Hayek reference, though it wouldn't surprise me in the least, and I'd very much like to see what you're thinking of if you can find it.
At least someone on the Internet recognizes the Mercatus Center for the Koch propaganda machine that they are. It's unfortunate, the influence they have on the GMU graduates.
My gamer and geek friends have been spewing libertarian flavored Randian nonsense since middle school, circa 1983. I never imagined that worldview would prevail. It was just so puerile. Not so different than the tortured coming of age fantasies embraced by the other subcultures (stoners, metalheads, preppies). Though maybe the nerds were more aggrieved, seeing themselves as an oppressed minority.
Of course, none of us knew about the well funded propaganda machine pushing the whole Austrian/Chicago school of economics. Young Republicans, trickle-down economics, John Birch Society, Hertitage Foundation, disaster capitalism, Grover Norquist, etc.
Edit: TL;DR: Mockery is the only appropriate response.
