Title, I'm a leftist but after reading some things on lemmygrad and here it seems I might have been lied to all my life. I have talked with some people from Cuba and Venezuela (expats) that support the west narrative about poverty and mismanagement. I "believe" that Russia is attacking Ukraine for selfish reasons and that China censors access to foreign information using the Great Firewall, please prove me wrong. Furthermore, it ultimately depends who do you want to believe or there are hard facts from reputable sources that are simply a hidden by the mass media?
EDIT: Thanks everyone for your very civil responses. I'll answer as many as I can!
Brainwashing is quite literally a myth popularized to explain Americans defecting to China during the Korean War as well as admitting to using biological weapons when the government denies it.
Brainwashing isn't real. The DPRK and China don't brainwash and neither does America (though it tried to learn how with MKUltra)
