These are basically the French equivalent of Trump voters who are finally revolting against the establishment. That's why the US media ignore these protests. If they were happening in Russia, Hungary or Egypt, it would be front page news every day and neo-cons would be demanding that we send troops.
When Egypt had their protests and they were against Hosni Mubarak, a US ally, the media were giddy about it. Obama couldnt get rid of Mubarak fast enough. The media loved it.
