One observation I've made about the Left vs. Right in the U.S. might be useful for further discussion. People in general have a hard time seeing the big picture and taking everything into account. People also have a tendency towards selective perception, so if you imagine each person's world view is like Swiss cheese with varying degrees of holes in it (and having the humility to realize this can be true even of people who have intellectual integrity to attempt balanced, big picture thinking), you then realize that each side can see the same issue or politician through vastly different distortions - depending on what is emphasized or overlooked.
I think it is important to encourage people towards big picture thinking, but to also accommodate the fact this is limited in human thought. This would pertain to social issues, but it struck me with particular clarity about environmental issues. I've noticed the Left will tend to focus on a detail that effects the big picture, but is still a fragment and limited in contribution. For example, straws. When it was discovered that these cause more problem as a pollutant than realized before, I had a number of liberal friends putting peer pressure to get people to stop using straws. I could appreciate it in theory, but could also understand why it could seem relatively hopeless to solve a problem and more a stance for moralizing. Culturally, I think people on the Right could accept an approach to the environment equally fragmented, but focused more on their local community. I think we need to give people constructive fragments that hit closer to home and have greater pragmatism and less socially defined moralizing.
When it comes to social issues there is a negative side to needing to view relevance of an issue through the lens of its impact on a local community and individual life, which is more of a mindset of the Right. The problem is that not all social issues occur at the local level. For example a rural, working class person on the Right may not knowingly have someone transgendered in their personal life, so that issue isn't real to them. The problem is the issue IS real for many, but they may perceive it much like the straw issue. In the working class, rural American, there is a tendency for reality to not exist outside of literal, individual experience and community, so these global issues need to be deconstructed down to that level.
It is helpful to think of this like an educator where you have to break down concepts into smaller pieces that people can comprehend and also show practical ways their effort will apply to their life. In the same manner students have tended to reject subjects where they say, "when will I ever use this in my life?", big picture thinking needs to be translated in a way people can understand through the limited lens of personal experience. The bottom line is that the two sides tend to fragment information differently and while the Left holds more of a value of global and wholistic thinking, it does not always apply and communicate it as such because it is also compromised of humans with limited, fragmented brains with selective perception.
No one enjoys being looked down on, and I think the rural, working class Right can feel like the Left finds abstracts and irrelevant issues to grand stand and moralize about as an excuse to look down on them. I'm not saying that is what is happening, but I think it can be seen that way. I am personally still horrified by Trump, but he was looked down on through the moralizing lens (with good reason), but I think that appealed to the demographic I refer to because they can feel like they spend their life working hard, with limited gains, and then the Left look down on them for reasons they don't feel are part of their life and experience but used as an excuse to disrespect them.
