Adstar, you are nothing but a tool of a godless and material civilization which aims to vanquish religion from the planet. The pseudo-Christian Western civilization is inherently Atheist and opposes God.
Had you more concern with truth you would actually read from legitimate translations of the Quran, rather than from propaganda websites which further demonizations and lies. The truth cannot be perpetuated by manipulations, God is on the side of those who are truthful.
In the verse you quoted, the word used is wali, which the translator wrongly identified as friends and protectors. Wali in Arabic means sovereign or an ally which has the advantage over you, the one who has affairs of the family or tribe, for example the father is the wali of his wife and his children. This verse can be applied to families and also to the realm of political treaties between nations. An alliance entered between Muslims and other nations should be that of equality, and not that of a weak party to a stronger party.
Quran
[5:82] ... And you will find that the closest people in friendship to the believers are those who say, "We are Christian." This is because they have priests and monks among them, and they are not arrogant.
[5:83] When they hear what was revealed to the messenger, you see their eyes flooding with tears as they recognize the truth therein, and they say, "Our Lord, we have believed, so count us among the witnesses.
It is important to read all the statements of the Quran, before we judge in a manner which is contrary to the truth. You should use wisdom in seeking knowledge, and hatred should not be a guiding principal in seeking knowledge.
Furthermore, Islam's ideological problem with the Christians of today, as opposed to the Christians of the past (whom worshiped only God) is that the Christians of today have made Jesus (peace be to him) a God, the son of God, or an aspect of God. God protect him from those whom make this charge. God is indeed one, this was revealed to Prophet Abraham (peace be to him). The nature of God does not change, it is constant Oneness. He is independent of creation. It might serve well to look into the fact that there were Christians (Arianism) who rejected the divinity of Jesus (peace be to him) in the early history of Christianity, eventually they were named heretics in the council of Nicea 325 AD and hunted by the Romans, who had recently embraced Christianity. A few surviving monotheistic Christians survived in the Holy Land and the Middle East up until the coming of the Prophet Muhammad (peace be to him) in the persons of the priest Basara, Salman Al Farisi (the Persian), and numerous others (the mercy of God be upon them).
“Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves. Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them. Not everyone that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? And in thy name have cast out devils? And in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.” (Matt 7:15-23)
Yes that’s true. Yes love everyone.
