It's hard because the one side genuinely views the other side to be full of bad people.
Republicans view the Democrats as lazy, selfish, jobless, entitled, whiny, hypocritical, unaware, privileged people who are genuinely mean spirited most often.
Democrats view the Republicans as sexist, racist, homophobic, xenophobic, greedy, closed-minded, arrogant and genuinely evil people most often.
I think both views are usually misguided.
I wouldn't even limit it to saying you need to listen to all viewpoints. You actually need people with multiple viewpoints to have a functioning society. It's the current Yin and Yang. I think the if you had a society with only conservatives it would result in a impersonal, hostile, every human for themselves type of society. If you had a society of only liberals, it just wouldn't work (for reasons I'm sure people in this thread already understand.)
Both views work in theory ("conservative" and "liberal") but both views suffer from the corruption of humans latching onto the respective vices that can be easily exploited in each view. You need people with the different ideologies active to hold back the vices of the opposing view so the positives of each view can be the dominant force. It's kind of like how you need competition between business to keep products desirable.
I mean, everyone rips into America and other "western" countries for being terrible and ugly, but let's be real. We're currently living in some of the best places to live in the history of the civilization. Something worked. And both sides have reasons to thank the other. I think passionate rivalry is necessary for society.
We just need to figure out how to fix the passion that turned into intense bitterness and anger, because that leads to unnecessary violence which all sides seem to agree is bad.
Also, I'm talking out of my ass kinda, but it was fun to just type something out.
