The statement is - True.
Most of the inter-faith conflicts are based on disputes about the differences of the faiths, which one is right and which one is wrong, who's deity is the real one and who's fake, the moral values, the principles, etc.
All around the world there's lots of religion based conflicts, be it between the Christians and The Muslims, the Muslims and the Sikhs, the Muslims and Hindus, the Muslims and the Judaism followers, the Muslims and the Buddhists, to name some of the few.
Even though it might come as harsh and selective, but the Islam seems to be the one that has problems with all other religions, while the others are much more tolerant towards each other.
