Yes the ideology that can come out of a mosque can be dangerous, that's the reason why muslim shouldn't be put aside of the society but on the opposite integrated so they blend in the population. And it's not by doing pointless votations about fucking constructions (just minarets have been banned not the mosqee) not even usable (and not even wanted by muslims present in Switzerland) that you integrate them.
The second thing is that this party is opposed to the formation of imam by Swiss university (like we do for protestant pastor) which could unable the control over the muslim faith instead of letting imam coming from Wahhabi gulf countries teach to moderate muslims coming from the Balkan.
Third thing is that it's an hypocrisy to say that muslims are dangerous and in the same time cooperate with one of the less tolerant muslim country which is using those weapons to spread his hainous faith and to repress his religious minorities.
