Here's a long but interesting essay by Sam Ennis and Anthony Resnick about Freedom of Speech as it relates to the Chick-Fil-A matter and beyond. A lot of people think the First Amendment guarantees them (a) the right to say something and be heard and (b) the right to say it and not have anyone suppress their speech by disagreeing with it.
My friend Roger says that Sarah Palin was fighting for the principle of Free Speech in this incident. Y'know, you're not really standing on principle until you defend the right of the other side to be heard. When you fight on behalf of your team, you're really just fighting on behalf of your team. When you fight on behalf of the opposing team, that's when you're standing on principle.
