Please, Islam was untill the 1900's one of the more peaceful religions. Look up during the crusades how both sides acted. Check out Ottoman tolerance. What happened to the Jews after the Spanish inquisition? Look at the technological advancements of Islam during the middle ages.
Saladin(Ruler who fought Richard the Lionheart during the crusades) was the first ruler since Cyrus the great that lifted the ban for Jews to live in Jerusalem.
The moors ruled over Spain and never exiled them or forced them to convert to Islam.
Islamic nations were most of time the victim of colonialism and imperialism during the 1800s-1900s. Hence the Idea we were at war all the time. The radicalism also developed in the 1800s before that we were equal or maybe even more tolerant.
There were times that the Dutch shouted that they preferred Islamic rule than the pope.

Hope you get the point, we are not a religion of 1500 years of violence.
