Allow me to rephrase:
Dear World,
France has been overrun with a type of person that has less than no respect for our culture or country and as we have seen in recent days many of them are prepared to literally burn our nation to the ground. Since the government has chosen to pretend this conduct is a legitimate expression of social grievances, and neither the police nor military seem capable of preventing mass destruction and violence, we find we have no choice but to shutter the Louvre until further notice.
Pity.
🇫🇷 Chers visiteurs, en raison d’un mouvement social étudiant, le musée est fermé pour le moment. Nous vous prions de nous excuser de la gêne occasionnée.
🌍Dear visitors, due to student strikes the museum is currently closed. We apologise for the inconvenience.
