Although I never noticed it at the time, many of her retorts to my arguments are simply name-calling. She loves to call me a "Tea Partier" (which while I agree with much of their platform, I've never attended a rally or event); she loves to call me a "Bushie," (which, although I greatly respect and miss him more and more, I'm hardly an apologist for him); she always laments "Faux News," and still thinks I listen to Rush Limbaugh and Glenn Beck, and has various and insulting names for those two. Lately, she's been calling me a "Romney-ite," whatever that means, and I've never made any reference to being a supporter.
Next time you see one of her posts, put your mouse over it and in the top right corner there will be a down arrow. Click it and select "Unsubscribe from X," which won't "unfriend" her, but will hide her updates from your news feed so you won't have to look at them. She won't know, and you'll be able to keep your sanity.
And don't forget to put one of these up next to your fall yard signs:
