Well there’s a careful balance needed. With close friends who are likeminded you can share your idea and maybe it’ll land, but once you’re addressing a larger group of people with an idea that goes against the stream …

You can, however, slowly change the discourse around you. Don’t partake, if the conversation goes towards fb or they send you a link respond with “oh, I dunno I’m not using Facebook anymore”. (Or alternatively “oh gee man, this link won’t load on my phone.”)

I’ve found that being hard out of the gate (“because fuck Zuckerberg!!”) doesn’t really work on people who are in there. What does work is presenting an alternative they can relate to “man I stopped scrolling fb because it’s such a waste of time, went for a walk today”. That’s neutral and wholesome and they can’t really object to that.

It’s not direct but subtle, now you’ve planted the idea that there’s people outside of the fb hive mind. People who might be enjoying fulfilling lives outside of fb.

Best of luck, you’re not alone in this fight.
