Let me elaborate on this tactic:
1) Postulate some crazy concepts about historical events until one gains a little traction either by morons or people who find it to be an amusing meme
2) Test the waters in different forums and social media spaces to see how folks react to this
3) If the forum crowd is determined to be largely left-wing and rationale, overamplify how "idiotic" people are for believing XYZ and then slowly begin associating these "idiots" with anyone they consider their social or political adversaries until you get large numbers of forum members to rant about right-wing "Trump-tards" (etc) and foam at the mouth about all their political grievances
4) Pretend to be a right leaning person, act like a jerk, and get your posts censored
5) Go to right leaning forums and show them that this "theory" is being censored and see if you can get them to integrate it into the larger narrative of "true things that the left is censoring". ( Eg, add it to the pile of Qanon nonsense ).
6) Return to the left leaning forums to mock the right leaning folks for doing step 5.
Mission accomplished, you've entrenched more poorly educated people into an absurd belief system and you've ignited a bunch of left-wing derision against them. This type of agitated polarization works well whether you are Putin, the Republican Party, Democrats, etc. Divide and conquer.
Here's a tip:
Nobody needs to grouse around about what "idiotic" things people believe.
If you don't like people believing dumb things, then create a blog, youtube video, or podcast explaining the topic in easy ( and friendly ) terms to those you wish to evangelize into the world of being "not idiotic".
The language of referring to people as "those idiots who believe" is a cancer that we suffer too much of these days with political propaganda organizations such as "Media Matters for America" (MMFA) who basically write a single set of political jokes about a daily topic and feed them to all the Late Night television hosts so that if you don't hear them say "republican person X did \ said this dumb thing" from one late night personality, you surely will hear it from another one and the version of what is told omits any nuance or rational counterpoint. In some cases, the words are out-right fabricated from out-of-context statements or things that MMFA thinks people will believe.
Here's a perfect example:
To this day, late night comedians treat the incriminating emails on Hunter Biden's laptop as "fake Russian slander" even though the New York Times has corroborated their authenticity and they are DKIM signed.
They use the laptop story as a talking point about how Republican's are "pro Russian idiots" even though nobody of either political party would be happy to have the son of a vice president using his father's position to arrange financial scams and deals with geopolitical enemies ( China ).
Because the latter information is largely invisible to over 50% of the US populace, it serves as a perfect place for political divide and conquer.
If the entirety of mainstream entertainment and news are gonna bury or distort legitimate news stories about their allies, what are the chances that anyone will vote for a moderate "middle" candidate?
The left will see right-leaning voters who discuss the laptop story as Russian traitors and the Right will see the left as "idiots" who get all their news from television comedians and insane "woke" SJW blue hairs.
People need to stop looking at the proles on the ground and start thinking about all the groups that are trying to pull the strings.
So I state again, this is no place for astro-turfers, propagandists, and non-linear warfare.
Nobody here really cares about what dumb things are floating through the brains of a small group of internet denizens. If these "idiots" grow in numbers, calling them idiots "louder" will not "cure" them or shrink their numbers. The only thing you will achieve is more entrenchment and polarization.
