What kind of attitude or mindset Non Muslims can expect from Muslims? To say that mindset of Muslims is or can be influenced by Koranic teachings of perspective of Allah towards Non Muslims is neither illogical nor uncommon sense. After all Muslims believe in infallibility of Koran. Lets see plethora of verses of Allah's view on Non Muslims found in Koran (By no means, the list of the following verses conveying stated message is exhaustive.):
003.032,YUSUF ALI: Say: "Obey Allah and His Messenger": But if they turn back, Allah loveth not those who reject Faith.
022.038,YUSUF ALI: Verily Allah will defend (from ill) those who believe: verily, Allah loveth not any that is a traitor to faith, or show ingratitude.
030.045,YUSUF ALI: That He may reward those who believe and work righteous deeds, out of his Bounty. For He loves not those who reject Faith.
002.098,YUSUF ALI: Whoever is an enemy to Allah and His angels and messengers, to Gabriel and Michael,- Lo! Allah is an enemy to those who reject Faith.
059.019,YUSUF ALI: And be ye not like those who forgot Allah; and He made them forget their own souls! Such are the rebellious transgressors!
058.020,YUSUF ALI: Those who resist Allah and His Messenger will be among those most humiliated.
002.161,YUSUF ALI: Those who reject Faith, and die rejecting,- on them is Allah's curse, and the curse of angels, and of all mankind;
009.030,YUSUF ALI: The Jews call 'Uzair 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 (Christians): how they are deluded away from the Truth!
010:100,SHAKIR: And it is not for a soul to believe except by Allah's permission; and He casts uncleanness on those who will not understand.
040.010,YUSUF ALI: The Unbelievers will be addressed: "Greater was the aversion of Allah to you than (is) your aversion to yourselves, seeing that ye were called to the Faith and ye used to refuse."
What this verse conveys is that on the Judgment Day all disbelievers will be lined up before the Hell and then disbelievers 'hate' themselves for not converting to Islam before, so here Angels tell disbelievers that Allah's hatred of you is more than the hatred you have towards yourself at this point.
If Allah hates and curses (personally I can not understand A powerful God cursing and swearing) disbelievers then what kind of opinions Muslims can have towards Kafirs. One can rest assured that those views and opinions will not be of kindness, understanding and tolerance.
