We all can agree situation and potential solutions are complex beyond imagination, but there is one place, one long term action that could solve most of this to some degree - proper mandatory education, based on proved science. Learn kids critical thinking, rather than raise another obedient generation who doesn't think for themselves and picks up a narrative from some place and then just sticks with it. Learning more soft skills at school (at which most teachers suck, but that's another topic), psychology, why people behave as they do, biases, how our childhood affects us all etc. I think generally our schooling systems globally need big rehaul, but for topic discussed, I can't imagine what I mention it wouldn't bring some improvement.
Teaching with current level of science as hard baseline is already a place where some western countries like US fail (ie evolution vs creationism topic).
I don't think the change I mention is in direct interest of many governments, so its more like a pipe dream and an additional burden on parents to drill this into their kids.
