Almost everyone I know, IRL and otherwise, is of a different political or religious persuasion than I am. I'm used to it. What really bothers me are those sappy posters with trite sayings... my kids say that people my age post them

I tend to ignore something on FB that is offensive. It happens very rarely though. If I get a friend request from someone I don't know very well I don't always accept it. Perhaps that is considered rude. I have unfollowed some people because of their feed content. They are people I don't know very well.
I will read all points of view but it must be presented in an acceptable manner.
I belong to Samoyed groups on FB. I love pictures of dogs and videos. I also belong to a fashion group on FB. I love that too. It is a very small group but we post a lot of pictures there.
I rarely post about my political and spiritual beliefs on FB. People who know me know what they are. DH is constantly posting about politics. Never about religion. He also posts a lot about music. He also writes letters to editors of newspapers. That is his thing.

Because I can access as much political nonsense as I desire in many other places, I limit my Facebook friends to those of similar views. It's much more amusing.

This is the year of political nonsense, I think. I limit my FB friends to just family (there are 52 of them), but still see some extreme views posted from time to time.
