I’m 100% sure there are massive propaganda (lies, hoaxes, half-truths, finger-pointing) campaigns funded by states themselves, either to keep their own power, or to get more power in other states. How does one fight them and not feel like it’s not worth the effort?
You cant fight it, you can only prevent it from reaching yourself and the people around you. The main channel for propaganda is conventional commercial media (TV, newspaper, radio) and social media(facebook, tiktok, twitter). You cant destroy those, you can only defend the people close to you.
