By 2025 the Muslims will be the majority in Europe, in Canada by 2030, the USA will fall in 2033. These are accuarial facts.
They aren't accuarial facts, they arent even accurate facts. Hell they aren't facts at all. They are presumptions you are making. But your presumtion is based on the idea that everything that is going on now will still be going on then. Rates will be the same. Growths, declines. etc. At no point in history has growth/decline rates ever been the sae one second than the next. Its a ridiculous assumption.
What happens if we have wars and global conflicts destroying the population?
What happens if we see pestilence and plague at an unimaginable scale that affects population?
What happens if peace and freedom break out across the world and being now free to worship as they choose, people choose something else?
What happens if the Lord decides to send Apostles to preach to the people with power and converts millions?
What happens if militant athiests/communists/socialists/(insert whatever you want here) decide to commit mass genocide and while out all religious people? Or just muslims?
Seriously, Michael Jackson has a better chance of becoming Pope than your "facts" do of being accurate.
