Since the 1990's 90% of all population growth in europe has been by islamic immigration.
In southern France, there are more mosks than churches. 30% of the people there who are 20 years old or younger are islamic. In other places of France like nice, marsilya and paris the number has grown up to 45%. By 2027 one out of five french men will be muslim. In just 39 years France will be an islamic republic.
In the last 30 years the muslim population of Great Britain grows from 82,000 to 2.5 million. A 30 fold increase. There are over 1000 mosks from which many of them former churches.
In the Netherlands 50% of all newborns are muslim and in only 15 years half of the population will be muslim.
In Russia there are over 23 million muslims, thats 1 out of 5 russians. 40% of the entire russian army will be islamic in just few short years.
Currently in Belgium 25% of the population and 50% of all newborns are muslim. The government of Belgium has stated 1/3 of all european children will be born to muslim families by 2025.
The german government has stated the fall in german population can't be stopped. The downward spiral is no longer reversible. Germany will be a muslim state by 2050.
You posted some false and dubious statistics. For example, the Muslim population of Belgium is about 6%, not 25%, and there's no evidence that Belgian Muslims are having ½ of all babies.
You don't need to oversell the reality of changing demographics of Europe: Europeans, by and large, aren't having enough kids to maintain or grow their populations, while their immigrant populations are.
