The English teacher convicted in Sudan of "inciting hatred and insulting religion" was, from published accounts, clearly doing nothing of the sort, at least not intentionally. At worst, she is guilty of naivety and ignorance, as many moderate Muslims have recognised.
If Muslim fundamentalists can get so worked up over a teacher innocently letting her class name a teddy bear Muhammad, it would clearly be dangerous to attempt to initiate a rational debate with them on far more questionable aspects of their faith, like the facts that the Prophet owned slaves and married a nine-year-old girl. These are issues that many distinguished Muslim scholars have wrestled with.
Not that irrationality is exclusive to Muslims; there are many Christians who are also incapable of handling any idea that questions their beliefs (dare I mention evolution?)
Personally, I believe if there is a God, He gave us brains for a reason. Any god who demands that we abdicate our intelligence in favour of blind submission is not a god I would care to worship.
