Look at that sign. "Mr. Pope be with in your limits." What limits? Classic Islamic law stipulates that Christians may live in peace in Islamic societies as long as they accept second-class status as dhimmis, which involves living within certain limits: not holding authority over Muslims, paying the jizya tax, not building new churches or repairing old ones, and…not insulting Allah or Muhammad. If they believe that a Christian has insulted them in some way, even inadvertently, his contract of protection — dhimma — is voided.

So are these protestors warning the Pope to behave like a dhimmi, or else? I expect so. After all, so many Christians and post-Christians in the West in recent years have been willing, even eager, to accept such limits — witness the chastened reaction to the Cartoon Rage riots, in which Church officials, government leaders, and others solemnly pontificated against "insults to religious figures." But it wasn’t really a question of blasphemy then, and it isn’t a question of insult now. It is a question of whether non-Muslims will submit to Muslim standards and restrictions on their speech, thought, and behavior.

And I hope that the Pope, for one, is not willing to do so.
