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.
That being said, I fully agree with the rest of your comment. This deficiency isn't new: Most people in any period of history have been unable to engage with ideas like adults, and there are a host of social technologies that prevent these infantile tendencies from blowing up society. Dramatic shifts in the way we live and engage with others (like those brought about by the Internet age) obsolete these safeguards, leaving this type of person vulnerable to a world of epistemological hazards until new tools and processes are created for them to follow by rote.
See how silly that sounds when you change the subject to something that we know is difficult. "Being an adult" is even more open ended. What does it mean, who defines it? Do you have to be "An Adult" to get elected to office and make rules that others have to follow? Is "An Adult" necessary to implement features on a website that dictate how people interact with each other?
I agree with your agreement statement. Infantile grownups in the past generally did not have a global audience in which they could wreak havoc with, and there issues tended to be local in context.
