One thing to remember when arguing about SOPA in a forum that encompasses a broader audience than Hacker News or Reddit is that not everyone is involved in the internet industry or even primarily a knowledge worker.
Think about how to appeal to someone who is retried or involved in managing a bakery or who runs a flower shop. We don't want to come off as a bunch of elitist nerds. We want them to understand that we're concerned about the future of innovation in this country and the preservation of free speech. We should focus on explaining how SOPA wildly oversteps the bounds of reasonable measures to prevent piracy and causes an enormous amount of collateral damage to the rest of the economy and innovation.

The store analogy was a pretty good start, IMHO.
