I had that epiphany in 2014, in the build-up to the Scottish independence referendum
when FB simultaneously suggested I might like a pro-independence page and a pro-union page. Not exactly subtle. It kept suggesting both types right up to the vote. I didn't click any of them.
My favourite was "Great Britain is under attack by Separatists!"
