There's plenty of "prior-art" to study when it comes to Islamification of countries - how it starts, what happens and what the results are. It's been repeated ad nauseam. The results are always the same and they are never good for anyone. The guise of doing patrols for people's benefit is how they fool people who are too stupid to see what is coming.
It's the extreme theological fascist version of socialism and just like socialism there are plenty of useful fools shouting "it will be different this time, it's never been done properly before, all the other times were anomalies".
I don't know if you're a fool or an Islamist, but you don't really have a counter argument because deep down you know it's true - you're just trying to obfuscate things.
Do your own research. Look at places like Afghanistan, Lebanon, Iran and other before extreme Islam took them over. Dare to claim that people there are better off or have better lives, especially women and girls.
Going off some of the sick manifestations with Muslim communities in western communities one can only imagine the horrors played out when they have complete control.
