Re: When in Rome
I imagine the downvote was for the naivety. It was indeed a perfectly reasonable assertion, however when dealing with religious zealots, "reasonable" is not in the vocabulary (or doesn't mean what we think it means).
From the extremist perspective, everyone else on this planet who is not ascribing to their value system/interpretation of their faith is a heathen who should be killed. Millennia of civilisation growth into a semi-mature set of nations with on-the-face-of-it fair laws counts for nothing.
To convince an extremist that they're wrong is a long drawn out process, and all the way through that process you'll need to keep them away from pointy things and opportunities to stick aforementioned pointy things in you. At the end of it, you'll then never be confident that they're no longer an extremist who wants to kill you.
