I feel the same way as you :'( (I'm from the same country, btw).
It's really frustrating how people seem to be so forgetful. But then again, it's not "forgetting" it's "brainwashing".
I'm currently in college. I chose a different university than my alma mater and now I think I made a good choice. I took a look at my works in high school, and I saw that there was a time when we had to write a criticism/review/whatever about the president then for a social studies paper. You know what I wrote? I wrote how this and that projects by that president was good, about how it's helping the country and all that shit. Then I remembered how our teacher then never actually mentioned how shitty his administration was, what its flaws were. And I, being the crammer I am, simply wrote that the administration's work is good because I don't understand anything. I have no idea what the consequences of his projects will be and I could only look at the news -shitty bias news which shows its supposedly "good" outcome.
I'm like "holy shit. I fucking wrote that?" Now that I'm in college, not gonna mention which (but I guess you could guess...), I learned each and every flaw his administration and its projects are. I learned about its good side too (albeit a it's a bit irrelevant to solve the actual problems in our country). I learned about how to judge whether something is indeed helpful (for our country), and which is not. Even without other people pointing out the flaws of whatnots (ex. 4Ps), I could see its flaws.
Well, long story short, only a small amount of our citizens actually get lectured about reality. They could only base their judgement from the media (shitty biased media) and from what they learned in school (although not everyone can afford education -but tbh, I believe most of those uneducated people from the marginalized sector know more than those that are educated, in regards to social and political issues).
P.S. Lucky you, I'm so bummed about how most, if not all, of my family (and friends not from my college) are so ignorant about social issues and when I try to lecture them, they either "listen" but don't actually care, or tell me to stop like what I'm talking about is black propaganda, that it's not real.
Well, that's that. I can't do anything to change our country (or the world) in an instant. I'm now a student-journalist for our school (activist) newspaper (or was actually, I quit because even though the people there are socially aware, smart and critical thinkers, they kinda talked bad about me behind my back (or so someone indirectly told me <
_< I can't help saying them when I'm angry.
