On the one hand, failry ridicoulous. On the other hand, don't make the mistake of thinking that all Muslims have the same theology or mores (or concerns about idols, which is actually a big deal in Sudanese religious politics), or that there aren't additional cultural implications when we're talking about a foreign white teacher from a former colonial power who is specifically there to spread Christian values. For that matter, while I obviously haven't met this particular women, I have met a distressing number of foreign aid or relief workers in Sudan (and elsewhere) who were complete idiots about local culture (got to especially love the ones who think that a week long seminar or some such makes them experts and then act entirely without humility). There's a differance between "I made a good faith effort culturally but missed this one" and "I'm a fecking twit who didn't bother to pay atention and maybe if they did stick me in jail for a year other people would think twice before being assholes who increase local tension and frquently manage to cause actual harm."
