I've always assumed that everybody on FB was checking everybody else out all the time, so therefore, I've never put anything up that was the least bit controversial and/or political.
You can rest assured that 90% of the folks who go on FB don't go there to check others.
I can't tell you how many times "old pals" chimed in asking me what I was up to and if I was still in my little hometown, back in Canada - when obviously, the answers to those questions are readily available to anyone who stumbles upon my profile; but people just don't read.
That's not mentioning those folks who simply send you a friend request w/o any message and never giving sign of life afterwards.
At any rate, you can always decide who gets to see what you post, on a per post basis.
