I would be super surprised if young muslims were any different than young christians and young-everything-elses in this regard. The increase in islam in europe is primarily from an influx of muslim immigrants. On the generational time scale, you can probably expect their children to become accustomed to universal culture[0] just like the rest of europe (and north america, and probably everywhere eventually). Because of continued migration, Islam will probably increase in absolute numbers for a while yet. But I doubt it will ever become dominant in regions where it is not already dominant. Being targets of missionaries from, e.g., Africa or South America (if they're more religious than EU/NA? I don't know?) would be a really interesting (to me) idea. Again, I'd be surprised. But interesting nonetheless! [0] https://slatestarcodex.com/2016/07/25/how-the-west-was-won/ https://slatestarcodex.com/2016/07/25/how-the-west-was-won/
