Most of my family is Conservative, but I have a liberal sister. We don't talk politics much since I am pretty politically plugged in and she isn't, so whenever she says "A" I usually have "B","C" through "Q" ready. Since she admits she really can't refute it she sort of gives up.
I can't really help her see the error of her ways, but she's a reminder that more people than not don't pay close attention to politics like we do on the boards.
