I’d unfriend her or block her. You will not change her mind, and you don’t need to read stupid stuff. I’ve had to unfriend a few people for racist comments, and for posting trashy comments on my wall about women we work with. I’ve also blocked someone keeps posting Sarah Palin fan club comments; I don’t want to read it.
I have to say in all cases, I don’t miss the contact with the posters. It’s like sticking your fingers in your ears and saying, “LALALALALA I can’t hear you.” Works for me.
@Jude, I would have to say that by her own concept of eternity and judgement, it’s most likely that she’s going to be in for a rude surprise and a warm afterlife. You can’t really improve on that. Somehow she’s missed the “Judge not lest you be judged” lesson. If the family’s into labeling family members, she could be “the mentally unbalanced one” that everyone makes exceptions for because she’s not right in the head.
