Adjust your privacy settings so that only Friends see your posts. It’s worked for me, so far.
thanks, yes, that was a wake-up and I did immediately adjust all of my FB settings to “friends only”
my friend, who is pretty much a libertarian, was totally disgusted with the other guy, who he’d only known a very long time ago in another place — couldn’t believe the guy would jump all over the page of a casual acquaintance (my friend) to viciously and irrationally attack a total stranger (me) over and over again
that’s one of the strange aspects of the “brave new world” of social media
