I fail to see how any of this crap is anything other than polite nationalist racism/essentialism, any more than the German bloodline nonsense, the shameful referendum that got passed in Ireland recently to tighten up the citizenship-by-birth rules that were allegedly being exploited by, oh, hundreds of refugees every year. This is subversion of French anti-clericalism to an agenda of fear of Islam.
Nationalism is by definition essentialist and racist at its heart.
The notion of French nationality that is being used is not racist (A salafist German asking for nationality wouldn't get it) not essentialist (the notion of equality of the sex being certainly new in France over the last 50 years). Un roi sans divertissement est un homme plein de misères
