Immorality and Crimes - both types of offenses erode societal fabric in the long-term. These perversions - if unchecked - will give birth to utterly shameless people who will not even blink while hurting others in any way or form.
Let us assume that You are a practicing Muslim and also have daughters. Unfortunately for You, a bunch of immoral people move in Your backyard. What kind of environment do You think these type of people will create in your locality? How will You make sure that Your daughters will not fall under their spell at some point? How will You convince Your daughters that Pakistan is supposed to be an Islamic Republic as per its constitution and you are supposed to be practicing Muslims in the face of perversions in your very locality?
Your Parenting will be at the mercy of Allah Almighty then.
When Holy Prophet (PBUH) began to teach Islam to pagan Arabs in Mecca, many made his life difficult in response and he (PBUH) had no choice but to migrate to Medina while in search for a much better environment to spread the word of one true God.
Environment matters in the end.
Food for thought.
