What is the point of Reciting Qur'an 33:51 & Qur'an 66:1-5 when Muhamamd & his Wives Died long back ago?

I'm tired of being told that Islam is a "Religion of Peace," when every day I can read dozens of stories of Muslim men killing their sisters, wives and daughters for their family "honor"; of Muslims rioting over some slight offense; of Muslims murdering Christian and Jews because they aren't "believers"; of Muslims burning schools for girls; of Muslims stoning teenage rape victims to death for "adultery"; of Muslims mutilating the genitals of little girls; all in the name of Allah, because the Qur'an and Shari'a law tells them to.
