French Council of the Muslim Faith proposes 'license to preach for Imams'

[Dystopia]

It's important to note that France has very different laws regarding free speech and the like compared to the US or UK.  Without knowing the specifics, I do not doubt that France has the power to do this.

OP's source includes a quote by "the head of France's leading Muslim body."  That troubles me, inasmuch as it suggests that the motivation is not solely a state-sanctioned desire to remove "hatred and incitement" and such but also a desire by some muslims to control which aspects of islam are propounded in France.

Franch's concept of free speech and secularism work differently than the US.

The first thing you want to know, is that France isn't just secularist but also promote laicité - In short, it is an ideology that attempts to separate as much as possible one's religious beliefs from one's personal life with others. So to provide two examples that show the difference between the US and France:

In the US, a student would never be banned from wearing a religious symbol in public school, because it is an expression of religious feelings. In France, it is banned because religious symbols don't belong in public school or any area of public sphere at all

It's normal in the US for politicians to express if they believe in god and what they think of religion, etc - In France, it's awkward and frowned upon to make religious statements about yourself, you need to keep it in private.

However, this isn't so much about religious freedom as it is about free speech and preventing terrorism. I dunno if people know this, but there's lots of UN international conventions signed by many countries to promote equality regardless of sex, gender, religion, race, etc - The US sometimes only signs but doesn't ractify, and sometimes makes reservations about certain articles - Many French laws like Holocaust denial and hate speech are actually a mandatory law by international conventions, it's not like France has a choice - Since hate speech can be criminalized in France, even if the French are usually keen on mockery and using free speech to promote unorthodox ideas, this is perfectly valid considering that hate speech isn't just white supremacists but also any person who preaches hate on others, including Islamic extremists. It is possible to do this, and it becomes urgent with the events in Paris. Moreover, I suspect more freedoms will have to be restricted in the name of security simply because there isn't a choice. BTW, being in a State of emergency, France can restrict citizens' rights more than usual because that's one of the advantages of declaring state of emergency.

So yes, France has the powe to do this without violating any international convention and even if state of emergency wasn't activated beforehand.
