Learn to Shut Up About Your Damn 99%

I am so close to unfriending an old friend on facebook.  I have known her for 12 years and she is currently divorcing my best friend.  My biggest problem with her is her recent shift in politics.  Now I am conservative and I don't really talk politics often unless someone asks me my opinion.  My friend has become more liberal which is fine because I don't believe that you have to the same political beliefs to maintain a friendship.  What really offends me is her constant posting of links that are about her political beliefs.  She has already done so many things that don't agree with lately that this is just the last straw.  I know that one day soon she will be off my friends list so maybe I can still be my friend.
