I think that is a very naive opinion and you are very mistaken but mostly only because you lack an understanding of how diabolical these systems actually are, how they work and are designed.

Its not that people could construct echo chambers (as some far off thought), its that they have, and they lied about it to you and everyone else (through omission and redirection), and they continue to do so regularly.

If you are on any kind of social media, you are always in an echo chamber.

I'm not going to go into all the arguments, you can do your own research, but the two that deserve the most attention are the optimization for engagement which optimizes for both positive and negative content and subversion aspect.

Have you ever heard of the Alt-right pipeline?

Its becoming fairly well documented, its basically a series of content that after watching, you are shown other content, and that content becomes gradually more and more extreme. Most of the time its very subtle (10 or more steps), and those algorithms and software are designed so you only see content that is optimized in this way, and they intentionally make visible objective video and history limited. You may notice previous watched videos disappear unless you know a direct keyword to locate them again, it was engineered as intended.

The way it goes, you might watch a video that pops to the Joel Rogan podcast for a guest speaker you are interested in, that then shows some interesting intellectual things with Jordan Peterson, and after a series of next content, maybe eventually you arrive at David Iccke and his talks about the greys and the reptilians (conspiracy of the Lizard Illimunati), QAnon, Neo nazis, or something else that are extreme or radical (and many steps removed). It sounds crazy, but its been documented.

Social media is the perfect propaganda machine, because its a 1 to many platform because there are methods in place to allow someone to dictate what you see, and limit what people see you say (amplification and de-amplification). Policies are geared to allow this weakness by design. You might notice the mass media does the same thing, and you'd be right, but they were less effective for this purpose.

As American's we aren't taught a lot about propaganda, which in my opinion does everyone a huge disservice because you can't recognize misinformation and propaganda without knowing what its goals are. Other countries unfortunately have also followed our lead in this regard. Its also difficult to punish entities that push it because its largely considered protected by free speech since Corporations are people.

Most people I've met domestically and abroad only have a very naive understanding of what propaganda actually is, and I haven't met a person who could tell me what its goals were when asked.

In other more restrictive countries its illegal, and the methods are taught (depending on the country) for their benefit, and it often goes by another name called subversion or more fully ideological subversion.

This has been used by all governments, historically, ever since WW2 as the nuclear age became too risky for outright conflict in a MAD world.

So non-alerting methods were developed to overthrow foreign governments without war, aimed primarily at manipulating the targeted countries citizens into unrest allowing a small minority to overthrowing the repressive regimes at little loss of life to the country performing these machinations.

It is sophisticated and subtle, its strength is it flies in under the radar, and it often employs many well-known psychological blindspots to do this which everyone has.

One of the primary targets is often the next generation's children because they lack the critical thinking faculties to discern the threat before age 12 due to developmental biology.

Cialdini wrote a book detailing many of those blindspots and examples where they've been used in his book called Influence.

The overall goal is, putting you into a psychological state where you can't react, or you react so irrationally that you jump at shadows with little provocation. The intended effect is discord and disunity, so no organized response occurs, and to corrupt aspects that make up a citizens national, religious, or moral identity since this leads to further discord and disunity and these people are unable to recognize truth from fiction in this irrational state.

In that kind of diabolical coup, those irrational people are almost always killed later, after a change has been instrumented to solidify the new normal (power structure).

If you were taught proper modern history (WW2+), you'd already know a lot of this, but I didn't get that sense from your response (hence my response). This is also why this topic and related references have largely been removed from public education, the same has also occurred regarding socialism's negative aspects in that sphere, and we are seeing a lot of conflict spawned from various movement sponsored ideals that lack true understanding of the underlying philosophy they subscribe to lately which is very worrisome.
