"You don't need to look much further than the Quran for proof that Islam is a peaceful religion"
Then read the following extracts from the Qur'an itself:
2:191-193 – “And slay them wherever ye find them, and drive them out of the places whence they drove you out, for persecution is worse than slaughter. And fight not with them at the Inviolable Place of Worship until they first attack you there, but if they attack you (there) then slay them. Such is the reward of disbelievers...And fight them until persecution is no more, and religion is for Allah.”
4:95 – “Not equal are those believers who sit (at home) and receive no hurt, and those who strive and fight in the cause of Allah with their goods and their persons.

8:38-39 – “Tell those who disbelieve that if they cease (from persecution of believers) that which is past will be forgiven them; but if they return (thereto) then the example of the men of old hath already gone (before them, for a warning). And fight them until persecution is no more, and religion is all for Allah.”
9:5 – “Then, when the sacred months have passed, slay the idolaters wherever ye find them, and take them (captive), and besiege them, and prepare for them each ambush. But if they repent and establish worship and pay the poor-due, then leave their way free. Lo! Allah is Forgiving, Merciful.”
9:29 – “Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, (even if they are) of the People of the Book [Jews and Christians], until they pay the Jizya [non-Muslim poll tax] with willing submission, and feel themselves subdued.”
9:111 – “Allah hath purchased of the believers their persons and their goods; for theirs (in return) is the garden (of Paradise): they fight in His cause, and slay and are slain: a promise binding on Him in truth...”
