They will be the happiest people in the entire world.
Will enjoy like anything, without rules.
Nonsense!
Muslims doesn't live only for world life. They believe hereafter life and they are very, happy to obey islamic rules. Non muslim people can't imagine and understant it
You would be astonished how many muslims suddenly feel free to do what they want when they don't have to fear other radicals treat them with stoneage punishment.
And really... young men coming from muslim countries as refugees only made a scandal in germany 3 months ago. A group of thousands gathered and stole from woman, touched them nastily and even raped some. Over hundred cases on this night in that one city and many hundred more in other cities too on that night.
Well, that happens when women have to be treated with religious rules like from the countries they are from. And surely only a fraction of the women are happy about their treatment in such society.
