You say idiots like you're immune. Every single one of us are experts in our own domain, but have neither the time nor the energy to become experts in all domains.
So we rely on other experts and the media to inform us, because that is historically their job. The media has unfortunately been co-opted by other interests, and has failed the public by spreading sensationalism and outright misinformation.
TLDR: Don't point the finger at your fellow man, point the finger at those who's job it was to inform them
