If you consider people as trolls, it's just an indication you object to views different to yours.
Depends on the views - starting with the question of whether they have any.
More likely, it's an indication that they have seen those people behave in a familiar and objectionable way. Bullshit is not the same as lying, after all - and the difference pivots on the relationships between the "views", the behaviors of those expressing them, and the relevant physical reality as repeatedly observed.
It's not the "views", if any, that decent people object to: it's the behavior. Jan 6 was an assault on the US Federal Government at its weakest point (liberal democracies depend on good faith commitments mediated by - who else? - media), an attempted coup that became ludicrous only when it failed (a common fate of attempted coups - and often a temporary one). The "views" of its perpetrators are an incoherent dumpsterload of ever-changing memes and fads - the behaviors sum to a focused, coordinated assault on the governance of American society.
there must surely be a group behind the scenes that actually knows what they are doing. Cabalist masterminds that will eventually succeed in controlling imbecilic myrmidons to puppet precision.
Unnecessary.
More to the point: Wrong direction - the comfort of paranoid delusion making sense of stochastic event and synergistic fuckup is not this generation of lefties' crib bedding.
The libertarian left in the US accepts - assumes, even - that fascists are fuckups at governance. We don't assume, for example, that the Iraq War was launched by people who knew what they were doing over the long term or in a larger sense. We do insist that the plotting and scheming and attempted masterminding behind that horrorshow of corruption and slaughter and State terrorism be recognized, its perps identified as a matter of historical record - the necessary information of democratic liberal governance.
The rightwing authoritarian monsters of the post-Korean War US political landscape are not farseeing and inhumanly capable masterminds. They are not products of dream and fantasy. They have names, vetted histories and interests and conflicts of same. They are observed, not hypothesized. They are not shadowy Elders of Zion, functionaries in some "deep State", but Kochs and Bannons and Dowds and Luntzes and McConnells and Breitbarts and O'Keefes and Sykes and Limbaughs and so forth and so on.
In contrast to the projections and introspectively derived stereotypifications of what we can now conveniently label the Republican (the co-opted Party, by circumstance, in our generation) media wing, this generation's libertarian leftwing conventional wisdom does not build from paranoia or necessarily presume omniscient evil-plotters, it needs no supernaturally capable puppetry to explain the successful media manipulations of the authoritarian Right.
The conventional wisdom of the Left these days leans into a different error, a more liberal "mis-underestimation": it tends to overestimate the role of innocence in stupidity, of obliviousness and incompetence in the short-sighted schemings of the greedy and power obsessed, of unguided emergent coordination in the effects of money thrown around at ideologically chaotic whim.
The voting base of the American fascist movement, the electoral foundation of the Republican Party, is not stupid (dull, repetitive, willfully blind, etc) by accident - as Dr Johnson observed of their kind, centuries back, to be quoted in Garret Keizer's essay for Harper's Magazine this past month: it's not found in nature.
It's made, not born.
