Indigenous Cathedral
A big problem with RW propaganda is it only fights at the superficial level—valorizing one-off leaders or events—rather than trying to make fundamental cultural changes (promoting capitalism, Hindu sovereignty etc).
At least, your biopics should emphasize the character’s RW ideas, rather than promoting him by relying on promoting how much jai-kisān Modi is or how Shivaji was fair toward Muslims.
(Outside of election contexts) promoting the clip of Modi saying “I feel pride when our businesses succeed” or Ajit Doval saying “as far as I’m concerned the entire country is right-wing” is infinitely more effective than appealing to existing left-wing or normie memes.
No great firewall can protect an impressionable mind.
You need your own Cathedral. A robust and credible network of sources of information and culture, pushing a coherent and appealing ideology, that has earned its place from the objective value it creates.
