But I acknowledge what you're saying about value of understanding other perspectives in conflict resolution. Funny enough, when I sometimes mimic the mindset of the group in question, I'm informed it's hella racist, which doesn't do them any favors.
I had departed from talking about specifically liberals and conservatives, but using example can help. As for the experience in working through the mindset of others, I think you've found your real motivation to combat it through reason. It might help to ponder, then, why their experience doesn't lead them to the information that it's hella racist, or I think more accurately, what else about that experience is appealing enough to ward off the feeling that it's hella racist. Personally I don't think it is some reason deficit.
I actually don't remember most of my childhood up to maybe 7 and hardly reminiscence much. If anything I'd say the last few years of life always shape me more so than those before, though I suspect that may be atypical.
Atypical? Not sure. I had done much the same in my life and hadn't put much thought into that until I began to appreciate the reasons why.
In any case, it's interesting to see how individuals react when faced with a grim reality. I find liberals tend to argue the case. While conservatives will often say anything to avoid doing so--perhaps we can probe what went on when they were kids to explain the rather degenerate behavior. This is nearly universal, as evidenced in the comment archive, which implies the categorizations are accurate & useful. Though personally I've always seen this division as a fundamental neuro/psych difference; there seems a range of mentalities useful to the survival of the species, and it makes perfect sense differing ones form fitting ideals for themselves & peers. I believe Moonbeam touches on that sometimes, too.
Here's how I see it:
Firstly, grim reality to me is defined as something that, if accepted, destabilizes a person's sense of who they are. Thus, while there is commonality in things that are likely to be grim, it is still very individual.
Everyone has a library that contains books on ways to protect themselves from grim reality. That library is generally very diverse, but there are certain books which are in easy reach and better written for different people.
People, though, won't try to ward off grim reality alone unless they have no choice. Thus, even if it's not the most accessible book or best written book, they'll pick a book that other people are reading if they can find safety in identifying with that group.
Of course, people also tend to choose groups that read books they like.
Having read War and Peace, you might understand how it is the best book to use for the grim realities you wish others would confront, but unless they work with intent to reorganize their library and exchange old titles, seeing how monstrous War and Peace is compared to their own selections will only push them to revere The Very Hungry Caterpillar more.
But, The Very Hungry Caterpillar is still a good book. I bet it's in your library somewhere in the back. Dust it off from time to time.
