Maybe you should start hanging out with her after sunset. Problem solved!!! LOL!!!
But seriously, it all depends. Can you eat somewhere else then meet her afterwards? Have you asked her if you could eat in her presence? What did she say?
Like you, I don’t think being a douche to make a point is productive. That being said there is no reason why you should suffer hunger or thirst in the name of someone else’s delusions. It is a call you need to make on your own based on the type of relationship you share and how you will fell afterwards with whatever decision you make.
The first thing that all honest students of Islam must admit is that it is not absolutely clear where members of al Qaeda, the Taliban, al-Shabab, Lashkar-e-Taiba, Hamas, and other Muslim terrorist groups have misconstrued their religious obligations. If they are “extremists” who have deformed an ancient faith into a death cult, they haven’t deformed it by much. When one reads the Koran and the hadith, and consults the opinions of Muslim jurists over the centuries, one discovers that killing apostates, treating women like livestock, and waging jihad—not merely as an inner, spiritual struggle but as holy war against infidels—are practices that are central to the faith. Granted, one path out of this madness might be for mainstream Muslims to simply pretend that this isn’t so—and by this pretense persuade the next generation that the “true” Islam is peaceful, tolerant of difference, egalitarian, and fully compatible with a global civil society. But the holy books remain forever to be consulted, and no one will dare to edit them. Consequently, the most barbarous and divisive passages in these texts will remain forever open to being given their most plausible interpretations.
