Macron is losing it; he must be pretty upset to have so many African countries abandoning France and taking their resources with them. People in Mayotte are upset because they don't believe France is doing enough to help them.
Not sure how Mayotte is a territory and not a colony (although maybe territory = colony but nicer sounding).
EDIT: Oh also the poverty rate in Mayotte is about 77% too.
Did they call him a racist? Is that why he is so angry? Or why does he immediately start his rant by making unnecessary comments about their skin colour?
