Raoul has a good point. It goes without saying that a large number of Muslim immigrants would naturally tend to be those who are sick to death of living in religious authoritarian nations, and are moving out when they can. Still, it also goes without saying that other Muslim immigrants actually are those who have the goal of turning European nations into religious authoritarian nations.

I don't know how many of each there are, and I don't think any poll could ever give us honest answers. I guess we just hope for the best, and before we condemn an entire immigrant group, remember it doesn't take very many rotten apples to make the whole barrel look bad.

It certainly wouldn't hurt to tighten up the borders and use more judgment on who to allow in. This would select for the good immigrants and help keep out the bad ones.
