Which I said - it's not neutral at all, nor is it about equality in terms of treating ideologies the same way.
It's not actually secular, in the true sense, at all, so that isn't a justification for it. Any justification is about maintaining a different cultural ideology.
I don't have an issue with the idea of cultural integrity. But I do think that if the state finds it's needing to position itself to draw lines around that, there are deeper issues. If it's Trying to preserve Frenchness in the face of high immigration, for example, it seems the problem is probably around immigration. Perhaps it's a reasonable approach there.
Trying to preserve language forms against organic change - I think that's probably the opposite of cultural preservation.
I mean, are we seriously suggesting that Catholicism isn't culturally French? If this state approved ideology isn't really secular, than really what you have is a promotion of one vision of Frenchness against another.
If the Catholics aren't supposed to complain, why should those who don't believe n gender ideology? Or to put it another way, if it's legitimate for a state to decide what constitutes the socially normative form of Frenchness for all, I don't see how they shoudn't treat gender GI the same way.
