This will be brief because the reasons aren’t complicated.
The political vitriol from all sides was getting old before Trump even declared his candidacy, let alone won the nomination and election. Facebook’s privacy policy is built on a shifting shoal and I don’t like trying to keep up with it. I’m tired of scrolling through the feed mindlessly looking at those “Tasty” videos, which for some reason I find annoying but hard to look away from, like when I’d pass through the living room as a ten or twelve year old child while my younger sisters were watching Barney, only to find myself sucked into it somehow, and then have some inane earworm stuck in my head for the rest of the day. And I’ve now seen enough photos of other people’s croissants to last several lifetimes.
It’s been a long time since I logged in and felt that I was getting any real value or enjoyment out of Facebook. So that’s why my account is disabled.
