When writing the SLIDERS script where Quinn meets Donald Trump, I asked Transmodiar to create Quinn's political opinions for me and Quinn/Transmodiar's views were decidedly not my own. My criticism of Informant isn't that I disagree with Informant on The Issues; my criticism is that he never seems quite content to let his personal opinions be his own but insists that his incredibly idiosyncratic worldview is universally objective.
This is my number one problem with politics and the worst thing that social media has done for the world.
Thirty years ago, people had friends that they'd chat with, they'd go to work, and that was about their social reach. Everyone probably had a crazy uncle with weird political views, but I'm assuming that societal norms kept most people from talking about their more radical political opinions. If someone talked about something that Reagan or Clinton did, you might test the waters on a political topic at the water cooler, hoping to see if the other person agreed with you. "Oh yeah, I don't like him." That would allow you to give your second-level opinion ("I don't like his policy on XXXX") but that's probably as far as it went. If the person didn't agree with you (or there were too many people around), you probably never get to that second level.
With social media, you can find a water cooler with people who think exactly like you. Not only that, you can find a water cooler for any opinion. You can wish people who don't agree with you into the water cooler cornfield. So you can start conversations with your second level opinion and get to third/fourth/fifth/Nth level opinions.
When that happens, you start to forget about the guy you wished into the cornfield who disagreed with you. You also forget about the guy you wished into the cornfield that agreed with you but not all the way. You didn't need his 99% agreement in your conversation because it made you question your beliefs and that felt weird and uncomfortable. Only 100% agreement at this water cooler.
So when you forget about the other side (or demonize them), you start to feel like all reasonable people are at your water cooler and anyone at any other water cooler is wrong. Or crazy. Or evil.
In a way, you can recreate your social world so that your opinion is the universal one. After all, you go to the water cooler and everyone there agrees with you. The water cooler is the only place you have social interaction so why wouldn't you believe that? Everyone you talk to agreeing with you translates to everyone in the world agrees with you. Everyone that matters, after all. Not those crazy, evil people who don't agree with you. We hate them.
