I would agree that media literacy is incredibly important.
I'm also concerned about hate-adjacent speech, the kind of prejudice that can percolate online where it becomes funny to make anti-Semitic comments or racist comments with friends in a joking way. I'm also concerned that the kind of polarization we see in our society is becoming reinforced by online algorithms that push young people especially toward content that is more and more at the extremes or margins of discourse, which then naturally cascades into exposure to more hateful material.
I think, beyond just literacy about the sources of news, the kind of education that's required is one that goes much deeper, actually, to recognize comments as prejudicial or potentially hateful before they get to an incitement to hatred or violence.
