I always thought it would make a lot more sense if Republicans were pro-choice (individual freedom, etc.) and Democrats were pro-life on a number of levels. It would eliminate a lot of contradictions for both parties.
I think it is funny, and a valid criticism of the fringe left. You could reverse the panels and it would be a valid criticism of the fringe right. Those of us in the middle recognize that most Muslims and most pro-lifers are peaceful, and that violent Muslims and violent pro-lifers should both be condemned equally.
