My little sister got married back in September. We're about a decade apart in age, so I missed out on a lot of her late adolescence/early teenage years while I was a teenager and away at college. We've never been on bad terms, but we haven't talked on a regular basis since the mid-aughts. Regardless, she's my sis, and we have always been pretty good buds, when we do talk.
In the weeks before the wedding, given that I didn't know the area where her and her fiance live, nor had I ever been to her house, and had no idea where the church was, I figured I'd do a test drive so as not to be late for her wedding.
I found the church without too many problems, then drove around in a rainstorm trying to figure out where they lived, while my GPS was cutting out every few minutes. I never quite succeeded in that.
What I did notice was that pro-Romney yard signs were abundant where she lives. Noticeably so. That fact was noted and mentally filed away, and she had an awesome wedding, and life went on.
Fast-forward to the last few weeks: In the last few weeks, my sister's posts on Facebook have basically turned into a non-stop screed of Fox News-fueled anti-Obama posts. She changes her profile pic and cover photo to some new "Obama-sucks" image several times a day. I don't recall my sis as ever having had any political opinion other than "All politicians suck", ever.
My quandary: Back in 2004, I got burned arguing with my Bush-supporting friends. I would score argument wins, they'd concede the win, but ultimately they voted for Bush. I now only have serious conversations with people who are either Dems/Libs or people who are of the "all politicians suck" variety. I have verbal sparring matches with Repub/Conservative friends who I know well and with whom I know I can have a fun troll-tastic fight, and still be friends. As such, I've ignored my sister's anti-Obama posts, because I feel like engagement is ultimately futile.
My Question: Any other kossacks out there have any opinions on how to interact with a sibling who has turned Fox News wingnut? I'm strongly leaning towards "ignore and move on", but I feel like engaging my otherwise-rational sister in a debate on substance and fact.
