Buddhists in Thailand, Jews in Israel, Christians in Indonesia, Hindus in India... Why is Islam at war with every major world religion, when none of these religions are at war with each other? Part of the reason is that the Qur’an is specific about the inferiority of other faiths (see 48:28) and the hatred that Allah harbors for their people.
Although it is common for Muslims to become upset about anyone “insulting” their religion, here is what the Qur’an says about Jews and Christians:
The Jews call Ezra a son of Allah, and the Christians call Christ the son of Allah. That is a saying from their mouth; (in this) they but imitate what the unbelievers of old used to say. Allah's curse be on them: how they are deluded away from the Truth! (9:30) (See also Bukhari 8:427), one of the last things Muhammad ever said on his deathbed was "May Allah curse the Jews and Christians.”)
The Qur’an specifically addresses Christians, Jews, Polytheists (Hindus) and atheists:
Christians are blasphemers (5:17, 5:73) who have invented a lie about Allah (10:68-69). Inventing a lie about Allah is the worst of sins (7:37, 29:68) and for this reason Christians are condemned to Hell (10:70). Although one (early Medinan) verse seems to say that righteous Christians will go to heaven, this is abrogated by later verses that make it very clear that Christians must cease being Christian (ie. reject the Trinity) or suffer eternal torment for their beliefs (5:72-73).
Jews are also cursed by Allah (5:13), in one of his final pronouncements. The Qur’an goes on to assure Muslims that Jews are wicked (4:160-162) – so wicked, in fact, that they have somehow managed to do the impossible (18:27) and alter the word of Allah (2:75). Jews are “fond of lies” and “devour the forbidden” (5:42).
The Qur’an assures believers that Jews and Christians have “diseased hearts” (5:52). Allah even takes credit for the enmity between them (5:14). Only Jews and Christians who submit to Islamic subjugation and pay the Jizya are protected in this world (9:29 & Ibn Ishaq 956).
Hindus are polytheists. Although Muhammad didn’t know any Hindus (and neither did Allah, apparently) the Qur’an still manages to lay the groundwork for the 1000 year ethnic cleansing campaign against the Hindu people that is estimated to have taken tens of millions of innocent lives. In Islam, polytheists are worse than all other religion. Those who join idols (14:30) or false gods (11:14) to Allah also invent a lie about Him (29:17) and will burn in Hell. Even believing in other divine entities along with Allah is an unforgivable crime (4:48, 40:12).
Atheists believe in no god, which is even worse than believing in the wrong one (Muhammad and his successors had atheists put to death - Bukhari 84:57). Merely questioning the existence of Allah is a testament to one’s impiety (25:21), even as Muslim arrogance is encouraged in the Qur’an. Muhammad always answered probing questions merely by telling the inquiring party that they would go to Hell if they didn’t believe in him (36:49-64). The Qur'an discourages Muslims from intellectual inquiry (5:101-102).
Anyone who gives up his religion is a “perverted transgressor” (3:82). Perverted as well is anyone who denies Allah (40:63). Freedom of conscience does not exist in Islam. Muhammad clearly prescribed the death penalty for apostates (Bukhari 52:260).
While contemporary Muslim apologists often speak of “dialogue” (meaning a unilateral arrangement in which they tell you about Islam while you listen) the Qur’an speaks of Jihad instead:
Listen not to the unbelievers, but strive (Jihad) against them with the utmost strenuousness. (25:52)
What would be the point in hearing anything a non-Muslim has to say... or even talking with them for that matter? Allah has already sealed their hearts and condemned them to Hell:
As for the Disbelievers, Whether thou warn them or thou warn them not it is all one for them; they believe not. Allah hath sealed their hearing and their hearts, and on their eyes there is a covering. Theirs will be an awful doom (2:6)
For those wondering why Allah would even make infidels if their ultimate destination is Hell, Muhammad said that the purpose of some (Jews and Christians, at least) was to take the place of Muslims, so that they would not suffer there (Sahih Muslim 6666).
