I agree that getting our aunts, uncles, etc to "get it" is very important. But I wonder if most of them even know this is an issue. Time for an anecdote:
While visiting my parents for Christmas, I scoffed when we drove past a car with a Lamar Smith bumper sticker (they live in TX). My parents asked me why I didn't like him; he was a stand-up representative as far as they knew. I mentioned SOPA and how horrible it is and they both drew a blank...turns out they had never even heard of SOPA. I was shocked since they watch the local and national news almost daily and discuss any story they see regarding technology/the internet with me.
