i'm not getting into a debate about that - it's irrelevant.
the law does not exist, whether the french language is under threat or not. although, i may suggest that population replacement (in conjunction with immigration control) is a better idea than fascism. and, i may ask the french people to reflect if perhaps their behaviour has something to do with the language dying off - forcing people to speak your language by gunpoint perhaps isn't the best tactic for wider adoption. you might find they tend to resist.
