actually outwith, the Quran is far more measured than that on the subject of other religions. that some of the people of the scripture are good people, and some of them are not good people. just like with all of us.
"Among the people of the Scripture (Jews and Christians) is he who, if entrusted with a Cantar (a great amount of wealth, etc.), will readily pay it back; and among them there is he who, if entrusted with a single silver coin, will not repay it unless you constantly stand demanding, because they say: "There is no blame on us to betray and take the properties of the illiterates (Arabs)." But they tell a lie against Allah while they know it." (3:75)
"Of the people of Moses there is a section who guide and do justice in the light of truth." (Quran 7:159)
"Not all of them are alike: Of the People of the Book are a portion that stand (For the right): They rehearse the Signs of God all night long, and they prostrate themselves in adoration. They believe in God and the Last Day; they enjoin what is right, and forbid what is wrong; and they hasten (in emulation) in (all) good works: They are in the ranks of the righteous."(Quran 3:113-114)
"Verily, those who have attained to faith [in this divine writ], as well as those who follow the Jewish faith, and the Christians, and the Sabians – all who believe in God and the Last Day and do righteous deeds-shall have their reward with their Sustainer; and no fear need they have, and neither shall they grieve." (Quran 2:62)
And there are, certainly, among the People of the Book, those who believe in God, in the revelation to you, and in the revelation to them, bowing in humility to God. They will not sell the Signs of God for a miserable gain! For them is a reward with their Lord, and God is swift in account. (Quran 3:199)
"Then We sent following their footsteps Our messengers and followed [them] with Jesus, the son of Mary, and gave him the Gospel. And We placed in the hearts of those who followed him compassion and mercy and monasticism, which they innovated; We did not prescribe it for them except [that they did so] seeking the approval of Allah. But they did not observe it with due observance. So We gave the ones who believed among them their reward, but many of them are defiantly disobedient."
(57:27)
