I do not partake in political comments on Facebook, or even Disqus. I limit my Facebook activities to those related to bicycle racing and fitness interests, yet I suspect that even on those subjects I my soon need to “tone it down” due to the prevailing view that those over 60 should not do excessive exercise.
I used to post lots of political commentary on FB. But no more. I do sometimes post responses to other’s political commentary. Mostly I just ignore political posts. I tend to lose respect for people on FB when I discover their political
leanings. I find that I am posting less and less on FB. Lately, like you, I just post running enthusiast stuff.
