I deactivated my first account 8 years ago, but got back on to re-connect with my old pals and acquaintances from back in the day. For that reason, it was fantastic.
After another year, I realized that I can't actually say ANYTHING interesting on this platform without offending someone. There's a lot of variety in my crowd. I have the sense IRL to know that not everything is for everybody, but that doesn't matter much on Facebook unless you want to spend hours and hours hand-crafting subsets of your friends for different topics (I don't). And I have zero interest in posting selfies or status updates of what's going on in my life, so that made the platform exceedingly boring and a waste of time for me. It's a shame, because it does work really well for "connecting" with people (in the shallowest sense of the word).
The only thing worse than people who are offended by everything is having to be afraid of offending over-sensitive people.

Which is a good thing. It's how it always was. You surrounded yourself with lots of different people with varying opinions. It's how you learned things. It was called being an adult.
Ruth Bader Ginsburg and Antonin Scolia were polar opposites on the issues. But they were also very good friends. Because they were adults. They weren't children who had to surround themselves with familiar things that reinforce their own views of the world.
I remember in college, we were encouraged to seek out differing opinions. I remember a guy who once chastised me for not seeking a broad enough range of opinions. He said, "What's wrong with you? Don't you want to be challenged?" My understanding is that sort of thing would never happen on a college campus today.
Be who you are. If people can't respect you for having a different opinion, they're not adults, and they're certainly not "friends," Facebook or otherwise.
This is a load of gilded age nonsense. There's never been any point in history where people deliberately exposed themselves to uncomfortable truths about people they considered other as part of "growing up".
I'd really challenge you to think about when you think this was. Was it in the 80s while gay people were dying of aids while straight people ignored their plight?
The 70s when mainstream american society treated anti-war activists as terrorists?
The 50s and 60s when white people literally moved out of cities and into suburbs to get away from black people?
What you're experiencing isn't "people failing to communicate with people with diverse views," but the internet finally forcing people to coexist with social groups they could just ignore until now. You have to exist on the same site as people who have been deeply harmed by the systems that benefit you and you're scared of that anger and those people's unwillingness to accept your desire to stick your head in the sand like your parents could.
At the same time that we are scoffing at the closed-mindedness of the past, in realms like politics, people were _better_ at working together across the aisle at some periods in History. Obviously, not the Civil War era, but for much of the early 20th century, as an example. Just because a lot of people are bad at something does not mean it isn't a laudable goal or practice.
