Yep here are some violent verses from islamic sources to prove it.
Qur’an 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, from among the People of the Book, until they pay the Jizyah with willing submission, and feel themselves subdued.
Soon shall We cast terror into the hearts of the Unbelievers, for that they joined companions with Allah, for which He had sent no authority: their abode will be the Fire: And evil is the home of the wrong-doers! (3:151)
Sahih al-Bukhari 6924—Muhammad said: “I have been ordered to fight the people till they say: La ilaha illallah (none has the right to be worshipped but Allah), and whoever said La ilaha illahllah, Allah will save his property and his life from me.”
Sahih Muslim 30—Muhammad said: “I have been commanded to fight against people so long as they do not declare that there is no god but Allah.”
Qur’an 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.
Qur’an 48:29—Muhammad is the Messenger of Allah, and those who are with him are severe against disbelievers, and merciful among themselves
And there is more! Islam is not peacful its far from it. I agree with you 100%
