I know it has been said many times but I still wanted to bring out his quote on this part. Islam condones every form of violence period.

Islam is a religion of tolerance, mercy and harmony. Its teaching do not contain terrorism, extremism, destruction, mocker, insults or rejection of any messengers sent by Allah... We also extend a further call for people to control their feelings, resist provocation, refrain from being rash and avoid imprudent actions and unrestrained reactions. Insults aimed at Allah's prophet and messengers do not cause them any harm since Allah grants them sufficient protection against those who may mock them. Allah speaking well of his Prophets is far greater than anyone else acclaiming them, and a pertinent instance of this can be found at the beginning of Surah Al-Qalam in the Quran.
