They actually hate the left more than the far right.
During this springs legislative campaign, they spent more time criticizing the left for being dangerous, proto-fascist and antisemitic than they spent criticizing the far-right for the same things.
Meanwhile a few far-right candidates were seen wearing nazi symbols or heard saying fascist stuff.
When choosing a prime minister, Macron chose one that the far right would approve (our National Assembly can refuse a prime minister and it’s government) instead of one the left would approve.
Macron and his cronies are just simps for our millionaire and billionaire overlords, and they know the far right in France is more than ok with economical neoliberalism.
Also, when a tool increases your productivity but your salary and paid time off don’t increase, it’s a tool that only benefits the overlords and as such deserves to be hated.
