No, I'm not saying they do or do not have anything in common. I had two thoughts occur to me in quick succession, and wanted to share them.
First, I wonder if the Ron Paul fans are falling into the trap of taking seriously anything Jon Stewart says? I suspect that any motive Stewart may have of highlighting media treatment of Dr. Paul would lie more along the lines of firing up the vocal minority of Paul supporters to cause noise and disruption, rather than having anything to do with affinity for any of Paul's positions.
Second, Han shot first. Think about it. His character development in the story is from being someone who cares about nothing but himself to being someone who realizes there are things bigger than the individual worth fighting for. When we first meet him, he's basically a good guy, but he would have no scruples regarding a "kill or be killed" life. It's only after his experience with the rebels that he is willing to risk himself for others.
