I think it's overall scapegoatong on poor immigration. It happens to be from Muslim countries currently, so they add the islamophobia on top to confirm the fear-of-difference bias. If they were somehow translated to North America by magic, they would be against Latino-Americans.

The irony is that Bardella is an Italian name. He has Italian and Algerian roots, at the time when Italians where the discriminated poor immigrants (same time as the Spanish and Portuguese during their dictatorships). But of course, for him, those were the good kind of immigrants who worked hard and integrated perfectly, while the new ones from Africa are lazy and free-riders.
