We have laws in our country to be able to do something against organized network of regilious people which would use their power as an organized group to take over some "components" of the country and keep that for mostly themselves (I guess in the economy). A sort of safe guard against religious in-betweeners.
Which country?
France, it is called "loi sur le separatisme religieux", if I am not much mistaken. It is very recent.
Mostly everything has 2 sides: it is totally illegal to discriminate based on religious matter, both ways.
