This sounds somewhat patronizing (the first part in particular), but falling victim to confirmation bias is something we all do. When ideas fit our own personal biases, we tend to become much less critical of them. For instance animal testing, when visible, is something very few people can emotionally accept. And there have been countless hoaxes [1] where people will share an image of an animal in one context (such as a rabbit suffering from severe hair less / skin damage at a veterinarian) and then claim it's an image of the result of a named shampoo company testing their products on animals. It gets people riled up and interested in stopping animal testing, but the problem is that it's completely fake. This is an obvious example but the exact same is true of words themselves and it spreads into everything -- most notably politics.
It's in many ways bizarre that we don't deal with this issue as a part of basic education. Imagery or messages designed to spark an emotional response are very effective against people who are not aware of what's happening. At the same time, they can be rendered far less potent by simply educating people about these tools of manipulation and giving them a wide swath of examples. In today's ever more connected world, with ever more people looking to shall we say 'utilize' other people, the complete neglect of this social skill in education today is perplexing.
