Some interesting commentary worth noting:
Indeed, not only does Islam, like traditional Christianity, assert that all other religions are wrong, but under Islamic law, Hindus, and Buddhists are so misguided that they must be warred against until they either accept the “truth,” that is, converting to Islam, or else being executed (Koran 9:5). As for the so-called “people of the book” — Jews and Christians — they may practice their religions, but only after being subdued (Koran 9:29) and barred from building or renovating churches and synagogues and a host of other debilitations that keep their (false) religious practices and symbols (Bibles, crosses, etc.) suppressed and out of sight.
From an Islamic paradigm — where Allah is the true god and Muhammad his final messenger — “intolerance” for other religions is logical and difficult to condemn.
