In cases of disagreement do you unfriend a person,or simply set your privacy settings so they can't see your posts and you can't see theirs unless you go to their page?

I had posted this nonsense thing that was rolling around in my head when I woke up:
Humpty Trumpty sat on a wall
Humpty Trumpty made a great call
...something something.

It was just dumb ditty.
This woman who I’d known growing up with…she lived in our neighborhood and she was my sister’s best friend growing up…said something about wanting to preserve our friendship but would I please stop insulting the right.
It gave me pause. There were so many different ways I could have responded. Part of me wanted to say, “OMG! You actually support that idiot? What is wrong with you!” But I didn’t. After some consideration I just deleted the whole thread, sent her a message apologizing and telling her I’d deleted it, then proceeded to add her to my “Friends except….” list! Ha ha!
I actually have about 5 people on there now. People I actually like for the most part, too.
