Not every Christian is necessarily a “good” Christian, following the bible to the letter and neither is every Muslim a “good” Muslim following the Qur’an to the letter. So even if the religions, from a technical aspect, contradict one another I still think the average Joe Muslim can get along with the average Joe Christian. Hardcore religious nutters on either side are going to throw hate but the mainstream semi-religious people ought to get along just fine with limited interaction.
