On the other hands, atheists are very bold about showing their contempt for the feelings of religious people, while claiming to be offended by the most innocuous religious display. Once upon time, this was not the case. Good manners , just good sense dictates that we treat others with respect, and not just atheists. Many a knife fight in a bar has started with a stupid insult.
Muslims have it ingrained in their Quran to not treat non-Muslims with respect. Their arrogance is produced purely as a result of it being sanctioned by their cult’s scriptures.
