The founder of Islam was 51, when he married the 6 year old Aisha, and he succeeded in having sex with her when he was 54 and she was 9. What can you expect from a religion founded by such a degraded person?

All the killings and rapes committed by Muslims in the world is due to Muslims following in the footsteps of the founder.

“That the Prophet married her when she was six years old and he consummated his marriage when she was nine years old, and then she remained with him for nine years (i.e. till his death).” (Sahih al-Bukhari 5133) 

“Narrated Aisha. I used to play with the dolls in the presence of the Prophet, and my girlfriends also used to play with me. When Allah’s Apostle used to enter (my dwelling place) they used to hide themselves, but the Prophet would call them to join and play with me”. (Sahih Bukhari 8.151)

“My mother handed me over to him, and at that time I was a girl of nine years of age…” (Sahih al-Bukhari 3894)

“The Prophet used to go round (have sexual relations with) all his wives in one night, and he had nine wives.” (Sahih al-Bukhari 5068)

“Allah granted Rayhanah of the [Jewish] Qurayza to His Messenger as booty [but only after she had been forced to watch him decapitate her father and brother, seen her mother hauled off to be raped, and her sisters sold into slavery].” Tabari IX.137

“Muhammad selected Safiyyah because of her beauty, made her his wife and gave a banquet at the wedding; then he had sex with Saffiyah at Sa`d-AsSahba..” (Sahih al-Bukhari 4.52.143)

Conclusion

Islam was founder by an evil person. The sooner the Muslims leave Islam, the better it is for the world and their souls.
