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.
We moderate ourselves differently at the bar, with our boss, with our wife's aunt. Maybe you don't drag contentious politics to your inlaw's dinner chat or sex anecdotes into work conversations. The OP's point is about applying this moderation across the board, because on FB everything is. This context breeds a culture of banality.
This website is discussing a broader and scarier implication, but the what the OP is describing is already at full (I hope!) maturity.
