I took my family to Tunisia on R&R from Saudi Arabia some 30 years ago. People thought we were nuts going from one moslem country to another during ramadan. We were very pleasantly surprised. They may have been moslems but they seemed at the time to pretty tolerant. The vast majority of guests at our hotel were Europeans, mostly French and German. One Tunisian bartender confided in me that for ramadan, they usually don’t drink wine during the day. Apparently all of that openness has changed.
You went to a country where Western tourism was an important part of the economy, which does a lot to encourage "tolerance". Today, the Salifis will do all they can to make Tunisia unsafe for Western tourists.
