Constrain your use to your business needs. I technically am on social media but inactive (unless we count HN, not sure I do). If I'm dealing with businesses that insist on using, say, FB then I go to their FB page and that's it. I don't view other people's feeds, I rarely look at my own FB wall page.
If you're posting to drum up business, then just post to drum up business. Stay out of the personal and political stuff which is mostly just drama and noise. Interact only with reasonable responses to your own posts and note when people are just trying to stir something up or troll, ignore them.
