> John Robison ... saw [the Masons] as a libertine, anti-Christian movement, given to the corruption of women, the cultivation of sensual pleasures, and the violation of property rights...
That is a pretty accurate description of where Europe ended up in the 1900s to today, so it seems a unreasonable to dismiss the man out of hand. 100 years for a big social project isn't that long a time given how slowly the world moved back then. It is reasonable to say that the Masons might have been a benign organisation - but they also might not have been. There is no contest that groups in Europe were trying and succeeding to push in that direction. The communists had their big breakout in the 1900s but the personality type always has and will exist and the intellectual groundwork was being laid at least as early as the 1850s.
There is this weird social dynamic where people dismiss the idea that radical change is possible in foresight then shrug it off and basically don't care in hindsight. It results in remarkably small groups being able to achieve some incredible things, but it is a bit frustrating an attitude to argue with.
The other problem is special pleading - the author adds more and more conditions on what constitutes the "paranoid style", until he's able to isolate the phenomenon to mostly the right half of the political spectrum. Meanwhile one can make a career of blaming everything on capitalism, colonialism, racism, or whiteness [1], and remain safely in the clear.
[1] And many have, e.g. https://en.wikipedia.org/wiki/Noel_Ignatiev or https://en.wikipedia.org/wiki/Susan_Sontag, employed by the very education system the author claims it is paranoid to believe contains traitors - sorry, not "contains traitors", the author deftly hedges it as requiring "the whole apparatus" to have fallen into enemy hands. An unusually strong condition, given it is applied to something so vague as a "style". I'd call it a strawman, if it wasn't written by such an eminent author.
The author already answered in the second paragraph:
"Of course this term is pejorative, and it is meant to be; the paranoid style has a greater affinity for bad causes than good. But nothing really prevents a sound program or demand from being advocated in the paranoid style. Style has more to do with the way in which ideas are believed than with the truth or falsity of their content."
Or here:
"In the history of the United States one find it, for example, in the anti-Masonic movement, the nativist and anti-Catholic movement, in certain spokesmen of abolitionism who regarded the United States as being in the grip of a slaveholders’ conspiracy, in many alarmists about the Mormons, in some Greenback and Populist writers who constructed a great conspiracy of international bankers, in the exposure of a munitions makers’ conspiracy of World War I, in the popular left-wing press, in the contemporary American right wing, and on both sides of the race controversy today, among White Citizens’ Councils and Black Muslims."

Yeah, there is a difference between blaming things on a shadowy tiny hidden cabal of vaguely-defined conspirators whose existence you don't even attempt to prove, and blaming... you know... the people actually in charge.
I mean, the people in power during most of the last centuries and decades have been white, racist, colonialist and capitalists. That's a fact. That is how they defined themselves openly.
So, you are in effect saying that "reality has a well-known liberal bias".
