This dilema is older than Islam. Does one sacrifice his rights or rights of a minority to defend the majority from some sort of threat, or does one allow that threat do destroy him and that majority?
My answer is yes, however such sacrifice must be based on the real and present threat, which the current crisis does not present us with, atleast not yet. Example of such (clear and present) threat would be a threat of existintial event, such as meterite crash. Or would you be against sacrifice of freedoms and liberties even under such threat?

Sure Muslims (and their subset - the refugees) are humans. The issue is that (in improbable worst case scenario) the values would be replaced with new ones, by the people who do not share them, as liberal western values (atleast in my opinion) are not universal or common.
However this is dependent on the lack of enforcement of local laws and customs and substantial change in population mix, which would not (in all likelyhood) occur.

As a conclusion - no, the immigrants crisis (atleast as it looks so far) won't destroy Europe, but yes, there is a requirement for an in depth response to it, as the crisis does create various problems, that must be solved, as otherwise the rule of law would be threatened.
