The point the OP is making is that nobody cares because nobody has been told to care. All it takes is a well-timed news article on how some Bad Guy used Irresponsible Unbreakable Crypto to change that.
I think that I'm more than capable of detecting most forms of propaganda, but I hold no illusions as to my ability to judge _everything_ that comes my way in a fully informed manner.
I can look back and see cases where too little information, bad information, or even just a misunderstanding lead me to believe in things that just weren't true. And I'm pretty sure I'm not the only one.
