Great question, wrongwayric, I was going to ask that myself. Under US law (if she said that here), prosecuting her for making an unpopular statement would be forbidden. Same if she said it about any other religious group. This is a fine example of why the government shouldn't recognize any religion as superior. Just because things work out when your religion is on top doesn't mean that'll always be the case. 20 years ago, the french would have probably laughed at the idea that this could happen.
This is why the separation of religion and politics is a Good Thing, because things change, and it's not always the religion you like that's in favor.
