Practical considerations are also the self-interest of a certain class with caste dynamics. Let's at least have the honesty of acknowledging self-interested politics is not so much an innocent ignorance but a cultivated ignorance. Ignorance as its own epistemology, etc. https://twitter.com/nuts2406/status/1300683647729635328
And I don't ever buy this "stories are fed to them." I don't buy simplistic media effects arguments -- nobody is a passive recipient of media messages. There are active caste/race, class, gender consciousnesses that enable certain kinds of engagement with the media.
If you think I'm mistaken look up the debunking of the magic bullet/hypodermic needle hypothesis (the actual name, lol). Media effects research for political messaging is a vast body of work that time & again proves people's responses to politicians are messy & complex.
Basically, don't be so quick to absolve our parents of their ignorance or justify their ignorance as media propaganda. There are a number of ways the Brahmin-savarna middle class operates to keep itself ignorant. We have to do the work, undoubtedly. But so do they.
