Ok, let’s break it down for you: What all 8 billion people in the world think does not matter to you. There are people out there cutting heads off in the name of religion, or people who think their dictator is a divine being.
People outside your country have little effect on your daily life.
Even people within your country have a weak effect on your daily life.
What other people believe only really matters for economic reasons. Still, unless you are very dependent on social safety nets even they don’t matter that much. You just find more money and carry on.
You might think that more propaganda will result in people voting for bad politicians, but it is actually possible to have too much propaganda. If people become aware of how easily fake content is generated, which they are rapidly realizing in the age of AI, the result is they become skeptical of everything, and come up with their own wild theories on what the truth really is.
The people whose thoughts matter most are the people you interact with on a daily basis, as they have the most capability to alter your daily life physically and immediately. Fortunately you can control better who you surround yourself with or how you interact with them.
If you turn off the conversation, the world will appear pretty indifferent even to things that seem like a big deal on social media.
