NBR: Need FB advice, WWYD?

So I have a friend on FB who is a friend from HS that I haven't seen since.  We chat back and forth on FB almost daily though.  Yesterday she posted something about how marriage is for men and women only.  I asked why she felt that way.  She went on and on about how this country is going to crap because people don't follow the Bible.  Her husband and father jumped in on the post saying that "I love my cat, should I be allowed to marry it" and that being gay was unnatural and other such nonsense.  I told them to enjoy their Kirk Cameron Kool Aid and went on my way.  Its bugging me now and I am thinking about defriending her.  WWYD?
