Should Europe accept more migrants?

[Jebus]

What are your opinions on this?

Somewhat ironically, the countries that are the most atheist and has the highest percentage of vegans are the ones accepting the most migrants. For example, out of the Nordic countries Norway is the one who accepts the fewest immigrants. It is also the most religious and has the fewest vegans out of the Nordic countries. Although I am not sure of the causation, I don't think this is coincidence as the same can be seen elsewhere in Europe.

Are you concerned that the world's most atheist countries accept so many highly religious people?

Are you concerned that once these migrants have settled and are generally better off than before they will begin consuming more animal products?

Although I don't believe that I, or any other Europeans, should have the exclusive right of living in Europe just because we were lucky enough to have been born there, I am generally against more migration because of my concerns with the two above questions.

I'm for migration if it means survival. It's a very tough question though as the more migration of say, Muslims, for example, the less atheistic a society may become. Granted that make take a long time, but considering the small size of many European countries, it might not take a long time. I'm thinking of countries like France here.
Is Norway the most religious Nordic country? I thought in was Finland.
