I think, from anecdotal personal experience, that a lot of people harbor deep seated emotions of anger, fear, and hostility. This makes it really difficult to communicate with them, as defensiveness and distrust are often a part of their reaction- and they sometimes lash out with personal attacks, whicb can beentally exhausting and discouraging.

Even with close family members, it is difficult for me to be able to explain my ideas without encountering a barrier in their reaction where they refuse to consider what I have to say.

I think, and this is just my theory, that a lot of people have traumas (sometimes ones they themselves don't realize relate to their associations with the subject being discussed) that make it hard to communicate and they may not know how to approach considering their view might be wrong, or even not wrong but just not the only valid way to look at an issue.

It's extraordinarily difficult to approach certain topics without also encouraging people to confront their biases and encourage them to question things they regard as absolutes- as I mentioned, even with close family members, it's very hard to communicate and have discussions.

It's not an easy thing for them to do, granted, and there is also very little incentive for someone to introspect on why they feel the way they do about something, even less for them to acknowledge there are alternate ways of approaching topics- even hypothetically.
