Could Muslims eventually outnumber Christians and Christian Secular people eventually in Europe?

Yes.

This seems to be the appropriate answer.

So, though helping the refugees who have been harmed by Assad and Iran that are Sunni in Syria and Iraq is a good humanitarian effort, the long term view of this is that because of the low Christian and Secular Christian birth rate in all of Europe Muslims may eventually outnumber Christians and Secular Christians in Europe by the end of this century. So, even though Vlad the Impaler kept Muslims out of Europe until his death by Muslims in 1476 or 77, Christians could be outnumbered by Muslims eventually in greater Europe if they take on too many Muslims as humanitarians now.

   Vlad was born in Sighișoara, Voivodeship of Transylvania, Kingdom of Hungary (today part of Romania) in... 

   
   

   Why is this true?

   
   

   I think it is a similar thing to Hispanic people south of the border in the U.S. coming across the border either legally or illegally to the point where there are more people of hispanic or foreign origin in California now than White people.

   
   

   So, this also could happen with legal or illegal refugees from the Middle East or North Africa during this century to Europe. 

   
   

   So, though they would not be (Invading) Europe like in other times they could control the vote in Europe by the end of this century because of the mess in the Middle East.

   
   

   I think that this is one of the reasons why many people are listening to Trump here in the U.S. about keeping Muslims out of the U.S.

   
   

   I don't really agree with Trump. But the problem I think is that similar to people coming up from over the border into California legally or illegally (who are mostly Christian) Muslims from the Middle East and Africa are coming legally and illegally into Europe which is slowly changing the balance of power there from Christian and Secular Christian to Muslim Sharia.

   
   

   So, this is something that is less of a problem here in the U.S. for now but it could become a very serious problem for Europe long term.

   
   

   The lack of birth control in areas south of the California border into Mexico and further south is one kind of problem but the Muslim problem completely changing Europe's governments is a completely different problem over the rest of this century.

   
   

   So, it could be that the complete lack of birth control and abortions in the Middle East will directly result (because of Syria and Iraq) and all the refugees, could change the balance of power changing by the end of this century from Christian secular to Muslim Sharia in Europe. 

   
   

   This might seriously change how Europe operates from then on away from the Christian secular way it operates now.

   
   

   So, this is something that both Europe and the U.S. need to think about now in what kind of legacy they are creating for their children and grandchildren long term both places.

   
   

   The main reason this might happen is just how many children Muslims tend to have compared to established Secular Christians or regular Christians in Europe.

   
   

   For example, in California, white people tend to have 1 to 2 children per couple but likely Hispanic couples might average 3 or 4 per couple because they are mostly Catholic.

   
   

   note:

   Hispanic people are obviously white too but I haven't figured a way to better talk about this difference yet. So, if you have please share it with me because I find the whole thing pretty confusing.
