Joe, I read the cartoon is an appeal against authoritarianism. Obama shows confusion on this point particularly when it comes to same-sex marriage. I see the nuns as showing Obama what's going on in the controversy between the nuns and the Vatican.

I see no reason why Catholic priests or nuns shouldn't marry or nuns become part of the priesthood.

Obama is doing his usual "playing it safe" role. The nuns are trying to widen his views.
