The assumption being made is that they’ll ditch the religion after four generations? I don’t see data for that assumption, maybe it is not 100%, but its certainly not as low as 20% apostacy.
Thus I would take serious issue with that statement, it is evidence of an ethnic or religious replacement.
And the actual numbers still don’t show a majority shift. Even if every Muslim in France kept their religion, they’d be ~10% of the population — far from "replacement".
Also, you missed the point entirely if the topic is “the population of x has gone from 1% to an estimated upper of 12.5% in 20 years” and your answer is “its below 10% right now”.
Not only are you potentially immediately wrong, since the number today could exceed 10%, it also doesn’t speak to how those demographics might be shaped by disparities in birthrates or continued migration.
But, you know that, you’re just trying to argue for some reason.
Either that’s a strong coincidence or vote manipulation is rife here.
Also anglicism is like, catholicism without a pope... also it was created by the king, not imported from another continent.
