Do you mean what makes the French Socialist Party a right-wing one? Support for neoliberalism, for worse working conditions, opposition to more democratic alternatives, taking their distances from actions led by common people (anti-cops protests, yellow jackets movments and more recently the 10th of September Block Everything action), etc. They are like living dead, both left and right at the same time : left in the official categories and alliances, right in their political orientation. They’re clearly not hard right conservatives, but they clearly are capitalists supporters.
Oh there seem to be some confusion here, my bad. My point was that PS (Socialist Party) is center-right, not LFI (which is left to my eyes and to most people excepting right wing fearmongers). I don’t know what you mean by communist supporters, if you mean people fighting for the worker’s rights outside of existing structures, then yes. If you mean leninist and derivatives, then not only : you’d have to include anarchists, libertarian marxists and close forms of revolutionary socialism.
