The question about Islam is, why do Muslims remain Muslim if they don't like violence, since Islam preaches violence in its writings? Rather, they try to do the difficult thing. They try to remain Muslim, and lie about the violence that Islam teaches.
You are right, these are the misconsepssions against Islam, unfortunatley spread by Mullah (Religious Scholar), just for thier own intrest. Today, the entire world views Islam as an aggressive and terrorist religion. Often, the killing of innocent people, suicidal bombings, and terrorist activities are carried out by people who claim to be Muslims, though in reality, the rebellious actions of these ignorant people have nothing to do with Islam. Rather, the real responsibility for these malicious and rebellious acts lies with the so-called scholars of Islam, who after the age of prophethood and Khilafat, were gravely mistaken in understanding the issue of Jihad, and considered the unjustified killing of human beings by sword a religious duty. These people, because of the distortion of their hearts, wrongly interpreting some of the Mutashabihat (complex and multifaceted) verses of the Holy Quran equated Islamic Jihad to rebellion, and associated self-concocted imprudent beliefs to Islam.
