I deleted my Facebook account when they said they were going to stop fact checking. I just made a post telling anyone who wanted to stay in touch to text me, gave them a week, then deleted the account. I've also been more politically active since leaving Facebook than I ever was before, as most major movements these days are using email mailing lists instead of social media groups.
I'm not going to say you have to delete Facebook or anything, but like, this sounds more like excuses than anything else to me. I have friends who still have Facebook who only keep it purely because they originally signed up for various apps and shit using their facebook account, and so they don't want to lose access to those things if they delete the Facebook account, and they are honest about it. I don't see them going around telling people like me that it is unreasonable to delete your Facebook account.
Also, it is 100% a personal decision to not use social media. You do not Need to be on social media. You don't need to be here, or on Instagram, or Bluesky, or anywhere else. You Do need real life connections and interactions. If you don't want to give up Facebook, fine, but don't act like it is an impossibility to make that choice, just don't make excuses man.
