Hating On Islam

Islam is a religious system begun in the seventh century by Muhammad (pbuh) . Muslims follow the teachings of the Qur'an and strive to keep the five pillars.
In the last few years, media have shared alot of videos showing terrorism happening in alot of countries, which is Isis, AL nusra, and many other terror groups.
But they never called them terrorists, they called them Muslims.
In many schools in Europe and the U.S teaches their students history, but they never show the Islamic history.
What's the real history of Islam, and why do people hate Muslims?
