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!
Any durable worldview is a huge interconnected mesh of self reinforcing stories, notions, and vibes. One or two contra narratives is not going to shake a worldview constructed of (I presume) 2+ decades of constant work done by western media. The more directly antagonistic the contra narrative the more the instincts you’ve been instilled with will treat it with hostility and neutralize it.
I think you would be better served reading the academic praise for The Jakarta Method and consider giving it a read.
A smaller time commitment; read about Project Cybersyn and the coup in Chile. Read the Nixon tapes transcripts.
Those won’t prove wrong any of the things you asked above but if you earnestly want to test your worldview, start building that new mesh.
