I am an independent and politically nonbinary, but people like assuming, almost always incorrectly, what I am thinking. The people on the right think I am left, and the people on the left think I am right. Apparently it is all relative, and the attitude of "if you disagree with me, you must be evil" is way too prominent, both on the left and the right.
I like listening to a variety of viewpoints because I can learn something new about human nature, even if I disagree with their opinion. It allows me to spot patterns that others don't see.
It also allows me to better understand and respond to flawed thinking and dangerous ideas. For example, giving power to someone who is power-hungry is dangerous, no matter what propaganda they are spouting. And there are opportunists and snakes in the grass all over the political spectrum. Just because they say the right things does not mean they do the right things. People don't always like it when that is pointed out. They confuse the leader for the cause.
The problem with remaining in an information bubble surrounded by like-minded people is that you start assuming that everyone thinks like you, which is usually not true at all. Both the right and the left fall into this trap sometimes. And people who have not experienced other cultures also fall into this trap. It creates an unrealistic and inaccurate view of the world. It also results in a shock when they realize that people on the other side of the world or from a different background think completely differently than they do.
It is one of the reasons why the Democrats lost the election in the U.S. They assumed they were the majority because they surrounded themselves with people who agreed with them and they repeatedly blocked or canceled anyone who disagreed. As a result, they shifted further and further away from what the people wanted, abandoned the working class, embraced unpopular views, and then wondered why they lost the swing voters, thereby giving the election to their arch enemies.
Cultivating and remaining in an information bubble is like shooting yourself in the foot and blaming the other side. The more you isolate yourself, the less reach your ideas have, and the less influence you have over society.
To be frank, some people are actually hoping both the far left and the far right becomes increasingly isolationist. It would mean they disappear from the mainstream consciousness since they silence themselves by blocking anyone who disagrees with them. That way they talk to themselves instead of bothering the mainstream middle, who are the actual majority.
The fact is, you don't hear much from the people in the middle because they get attacked from both the right and the left, and most people don't like the drama. Instead, they just go to the ballot box and vote against the politicians they don't like.
In an idea world, we could talk about the issues and come up with some non-partisan solutions. But society has become so polarized, I am not sure that is even possible anymore.
