Why is Italy welcoming Islamic migrants who openly support murdering girls, having sex with children, and even forcing marriages

Why is Italy welcoming Islamic migrants who openly support murdering girls, having sex with children, and even forcing marriages with little girls as young as six? WHY!? After an 18-year-old Pakistani Muslim girl living in Italy was murdered by her family because she refused a forced marriage to her cousin in Pakistan, they killed her not only for challenging male Islamic authority but also for becoming too Westernized. Italian news interviewed members of the Islamic community in Rome to find out what they thought of the young Pakistani woman killed by her family.
