If it's any consolation, my 16y.o thinks that fb is garbage and nothing but a place where drama is created. There's better platforms out there.

I think that you are well within your right to expressly state that you won't be discussing politics and that blocking/unfriending is a viable solution. My father a best friend's mom had it out on my page. I was floored. Totally trapped in the middle. I don't even recall what I posted, I don't recall it being remotely inflammatory. I had words for my dad and apologies via text to my friend's mom. As my son says....a place for creating drama. Much like the unenviable situation that you're in.

Went to a family function, one niece and I discussed whether we were or not because that's not the means of communication. It's an ok place for group invites such as her upcoming baby shower. I'm upfront about chances are I might not be following the day to day stuff. It's for updates etc with out of state family.
