Wa alykum as-salam brother
How about starting with Religious freedom supported by the Quran and the hadith's call for killing non-muslim untill they believe, and for killing apostates? A thing that not only accepted but widly practiced by Muslims throghout the history and untill now.
Let there be no compulsion in religion: Truth stands out clear from Error: whoever rejects evil and believes in Allah hath grasped the most trustworthy hand-hold, that never breaks. And Allah heareth and knoweth all things.
If it had been thy Lord's will, they would all have believed,- all who are on earth! wilt thou then compel mankind, against their will, to believe! .

Hadith
Narrated Ibn 'Umar: Allah's Apostle said: "I have been ordered (by Allah) to fight against the people until they testify that none has the right to be worshipped but Allah and that Muhammad is Allah's Apostle, and offer the prayers perfectly and give the obligatory charity, so if they perform a that, then they save their lives an property from me except for Islamic laws and then their reckoning (accounts) will be done by Allah."
Narrated Anas bin Malik: Allah's Apostle said, "I have been ordered to fight the people till they say: 'None has the right to be worshipped but Allah.' And if they say so, pray like our prayers, face our Qibla and slaughter as we slaughter, then their blood and property will be sacred to us and we will not interfere with them except legally and their reckoning will be with Allah." Narrated Maimun ibn Siyah that he asked Anas bin Malik, "O Abu Hamza! What makes the life and property of a person sacred?" He replied, "Whoever says, 'None has the right to be worshipped but Allah', faces our Qibla during the prayers, prays like us and eats our slaughtered animal, then he is a Muslim, and has got the same rights and obligations as other Muslims have."
Narrated Qais: Jarir said "Allah's Apostle said to me, "Won't you relieve me from Dhul-Khalasa?" I replied, "Yes, (I will relieve you)." So I proceeded along with one-hundred and fifty cavalry from Ahmas tribe who were skillful in riding horses. I used not to sit firm over horses, so I informed the Prophet of that, and he stroke my chest with his hand till I saw the marks of his hand over my chest and he said, O Allah! Make him firm and one who guides others and is guided (on the right path).' Since then I have never fallen from a horse. Dhul-l--Khulasa was a house in Yemen belonging to the tribe of Khatham and Bajaila, and in it there were idols which were worshipped, and it was called Al-Ka'ba." Jarir went there, burnt it with fire and dismantled it. When Jarir reached Yemen, there was a man who used to foretell and give good omens by casting arrows of divination. Someone said to him. "The messenger of Allah's Apostle is present here and if he should get hold of you, he would chop off your neck." One day while he was using them (i.e. arrows of divination), Jarir stopped there and said to him, "Break them (i.e. the arrows) and testify that None has the right to be worshipped except Allah, or else I will chop off your neck." So the man broke those arrows and testified that none has the right to be worshipped except Allah. Then Jarir sent a man called Abu Artata from the tribe of Ahmas to the Prophet to convey the good news (of destroying Dhu-l-Khalasa). So when the messenger reached the Prophet, he said, "O Allah's Apostle! By Him Who sent you with the Truth, I did not leave it till it was like a scabby camel." Then the Prophet blessed the horses of Ahmas and their men five times.
It is narrated on the authority of Abu Huraira that when the Messenger of Allah (may peace be upon him) breathed his last and Abu Bakr was appointed as his successor (Caliph), those amongst the Arabs who wanted to become apostates became apostates. 'Umar b. Khattab said to Abu Bakr: Why would you fight against the people, when the Messenger of Allah declared: I have been directed to fight against people so long as they do not say: There is no god but Allah, and he who professed it was granted full protection of his property and life on my behalf except for a right? His (other) affairs rest with Allah. Upon this Abu Bakr said: By Allah, I would definitely fight against him who severed prayer from Zakat, for it is the obligation upon the rich. By Allah, I would fight against them even to secure the cord (used for hobbling the feet of a camel) which they used to give to the Messenger of Allah (as zakat) but now they have withheld it. Umar b. Khattab remarked: By Allah, I found nothing but the fact that Allah had opened the heart of Abu Bakr for (perceiving the justification of) fighting (against those who refused to pay Zakat) and I fully recognized that the (stand of Abu Bakr) was right.
It is reported on the authority of Abu Huraira that the Messenger of Allah said: I have been commanded to fight against people so long as they do not declare that there is no god but Allah, and he who professed it was guaranteed the protection of his property and life on my behalf except for the right affairs rest with Allah.
It is reported on the authority of Abu Huraira that he heard the Messenger of Allah say: I have been commanded to fight against people, till they testify to the fact that there is no god but Allah, and believe in me (that) I am the messenger (from the Lord) and in all that I have brought. And when they do it, their blood and riches are guaranteed protection on my behalf except where it is justified by law, and their affairs rest with Allah.
It is narrated on the authority of Jabir that the Messenger of Allah said: I have been commanded that I should fight against people till they declare that there is no god but Allah, and when they profess it that there is no god but Allah, their blood and riches are guaranteed protection on my behalf except where it is justified by law, and their affairs rest with Allah, and then he (the Holy Prophet) recited (this verse of the Holy Qur'an):" Thou art not over them a warden" (lxxxviii, 22).
It has been narrated on the authority of Abdullah b. 'Umar that the Messenger of Allah said: I have been commanded to fight against people till they testify that there is no god but Allah, that Muhammad is the messenger of Allah, and they establish prayer, and pay Zakat and if they do it, their blood and property are guaranteed protection on my behalf except when justified by law, and their affairs rest with Allah.
It Is narrated on the authority of Abu Malik: I heard the Messenger of Allah (may peace be upon him) say: He who professed that there is no god but Allah and made a denial of everything which the people worship beside Allah, his property and blood became inviolable, an their affairs rest with Allah.
