But you can bet we are going to keep discussing Tian'anmen Square instead of Pinochet’s dictatorship, Jeju Island massacre, Indonesian anti-communist purge, etc. It's as if the average person believes anything so long as mainstream media says it.

What's stopping a re-examination of historical cover-ups? I think you answer your own question when you say: where's a good place to discuss this without going into conspiracy spirals? I mean that any time topics like this come up, people who are sincerely interested have to constantly militate against the "conspiracy theory" stigma. If you're hit with that label, you're persona non grata in academia, news media, and mainstream accounts on social media. That's what stops people. The places to discuss conspiracy adjacent topics would be alternative platforms like this, until news media slowly come around on accepting anomalies many years after the fact: Jack Ruby did have mob ties; the Saudis did seem to fund hijackers, etc.

You know that Watergate, Iran-Contra, and Iraq are settled history at this point, right? They are no longer contested by serious people. A better example might be the JFK assassination & cover-up, or better yet, ongoing events like the astroturfed Mexican “gen-z revolution” or the fake Venezuelan “narco-terrorism” the US made up in an attempt to overthrow president Maduro.

Where are good, constructive places to discuss these issues without falling into unproductive conspiracy spirals?

The fediverse, which for the most part currently isn’t run by corporations or by NGOs funded by governments or corporations. There are also a few independent, non-corporate, non-NGO investigative reporting sources. I can name a few good ones if you like. People on lemmy.ml often post articles from them.

Because it's ideologically useful for liberals to not:

Wait, what is this about who beat the Nazi's?

What’s stopping a sustained, constructive public inquiry into these parallels between past cover-ups and current information control?

There is no mechanism to promote the investigation. At best there will be queries like you made for the general, and social media reactions to specific events as they unfold.

A large chunk of government, politics, and press in the USA no longer exists. There are no authorities to turn too, now or later, regardless who gains power in Washington.

Most of the Anglosphere outside the USA is in a free fall too, a few years behind, maybe 20 years.

Most of the past ones have been admitted and are out in the open. A few big ones like JFK and 9/11 remain.

Tucker Carlson did an Interesting 9/11 series recently though (no I don't endorse Tucker Carlson as a whole)

We never trusted the media either way it goes. History is written by the winners so how do we decide what really is history or propaganda? Without time travel at the end of the day everything is subjective truths

Plenty of serious investigative journalism still going on around these subjects, but it won’t be openly discussed and acknowledged by every political faction and strata of society in America until after the empire falls, is replaced in its primacy by some other global power, and the ruling factions are removed from power. Look at how the British now fairly openly admit the atrocities committed by their ruling factions when they were the global superpower. It doesn’t just become acknowledged out of the goodness of the people’s hearts, it becomes undeniable.
