According to western liberal media. 16% of french support ISLAMIC STATE (not Islam or particular customs mind you, but genocidal state already existing in the middle East), it is closer to 27% among those younger than 18, reflecting the fact, that religious people do have far more children than their secular counterparts. Outbreeding them. Then you come along and tell me, that caliphate in France is non-option, because... why exactly not? Do you think those people cannot use voting booths?
That is alarming. This also means that a majority of the Muslims in France are supporting the ISIS. Considering that the Muslims are around 30% of the population in France, this poll means that more than half of them are solidly behind the ISIS.
