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.
The frustrating (and silly) thing is that this argument is used a lot to attack left-leaning folks who _do_ engage with many people whose experience and world view are very different from them... like people who are homeless, immigrants from other countries, people who are racially minoritized, people who are disabled.
For many people who don't experience those kinds of life experiences, building relationships with those folks can be really tough and bring into question a lot of the foundations of their world view.
The argument that left-leaning people won't engage with right-leaning people often feels like it's used as an excuse for right-leaning folks to use rhetoric and hold positions that routinely disenfranchise and threaten the safety of the kind of people that left-leaning people have worked to empathize with and build relationships without consequence. That the people who continue to have right-leaning views don't seem interested in putting in the same _effort_ to empathize and build relationships with people other than themselves is both hypocritical and not surprising to me.
Finally, engaging with "challenging" opinions is all well and good as a mental exercise, but building and maintaining a relationship with someone is a project that requires continuous work (even as just a friendship) and I think it's worthwhile to be selective in the people who you put in that kind of work for.
How much would a white left-wing person be willing to debate with e.g. a conservative immigrant? Would they treat them as an equal, or even defer to their lived experience? Or would they simply find another, less conservative immigrant, who would not oppose their world-view, and choose this one to be the speaker for the minority?
In my experience, there is not much difference between left-wing and right-wing people in willingness to help oppressed people. Seems to me they mostly differ in style: a left-wing person would probably create a non-profit organization and also write about what the government should do, a right-wing person would probably work under the umbrella of some religious group and also write about how individuals should help themselves and each other. On each side, a few people would actually do something, more people would talk about how someone else should do something, and most wouldn't really care. I am not saying the sides are exactly balanced; I am just saying empathising with people (but also twisting their opinions to better fit your ideology) exists on both sides.
(By coincidence, today I saw a debate where a strongly left-wing person dismissed some complaints of a marginalized person as "anti-scientific", without actually addressing the substance of their argument, just because that person disagreed with some organization that has a mission to help this marginalized community. No more detais, because it happened in a private conversation, it's just a funny coincidence that first I read this, then I switch a browser tab and read about how empathetic left-wing people are. Some of them are, some of them are not.)
