Facebook has created a system that encourages fake content. Change that system and you get rid of the content.
Stories that challenge a person's world view are generally ignored, stories that support a person's world view are liked.
I enjoy casual conversations with people i disagree with. In person i can keep it genial and friendly. On line i don't have that control, and criticizing an idea becomes tough to distinguish from criticizing the person. Because the person i'm interacting with isn't really thinking much at all, and just reacting in an emotional way.
At least that's how i believe they're reacting, because i catch my self reacting that way more often than i like to admit.

As a concrete example, I've had a bunch of in person conversations about gun ownership, and a fair number of online discussions. With the in person examples, generally, i feel like i've learned something, and my interlocutor has a better understanding of my point of view. Any time i try that online, i just get pissed off and i'm pretty sure my interlocutor does as well, judging by being unfriended.
That kind of response died along with USENET in the 90s in the eternal September
I've had the same experience.
I'm a gun owner. I also believe that guns are dangerous and every gun owner should be thoroughly vetted before being allowed to own one.
As a New Yorker it took 11 months for my pistol permit application to be processed. My finger prints were taken, as well as a mug shot. It cost over $100. A county sheriff came to my home to inspect it and interview me. And I was fine with all of that, because it meant others had to go through this same strict process. I think it should not be easy to obtain a gun, and it should be easy to lose the privilege.
But I've shared this opinion online with other gun owners before and to say it was not received very well is a massive understatement. Apparently, not only does my belief in tighter restrictions mean I don't deserve to own guns, it also means that I don't believe in any part of the Constitution at all, and should my life be in danger, gun owners who may be able to help me shouldn't come to my defense. That was seriously what I was told. To these people online it's preferable that I be killed than defended because I believe guns shouldn't be easy to obtain. It's absolutely crazy.
But now you can interact orders of magnitude faster and with more people with it, thus changing the nature of interacting.
