I have a LOT of FB friends, and I find that some of them, a few, continually post politically radical views with which I disagree. It's disturbing, and I, of course, do not respond. I've used the "unfollow" feature with those folks, just to avoid seeing their posts. They are not "unfriended," and still remain on my friends' list. But I suspect something on FB reveals to them that I've done this. I have no idea why or how, but I think it's the case on FB.

I never post personal things on FB, just mostly friendly pics of animals, inspirational sayings, sometimes of my travels, and my art. The folks I've "unfollowed" no longer respond, and that's why I think somehow they know. That's okay, I guess. When I check their FB friends' pages, they are still active, posting their political rants. I would never post such, as my friends are a very varied spectrum of politics, and I wouldn't offend. Why do these folks think it's okay to do such?
