Say it isn't so, but most dKos readers have given up the strum und drang of political debate with their rightwing friends and kin. In last weeks's straw poll approximately one-third of dKos readers no longer sustained these relationships, while 50% had entered a zone of silence or one-way communication. Only 10% had open, two-way dialog.
There were many insightful and poignant accounts of fractured relationships. It struck me that the two biggest obstacles to communication were a separate "fact" set and a profound divergence in values. Makes sense that you're not going to get very far if you can't agree on what's true and you don't want to get to the same place anyhow. Several commenters recommended Snopes.com, which is always worth a try even though, as they say, you can lead a wingnutter to reality but you can't make them live there.
