James Farmelant has argued here that there is an element of functionalism in Marxist explanations, and I agree with his take on this. Until we win, we will continue losing. That's tautological & hardly interesting, but consider a more complicated form of the same: until capitalism is abolished, any reform the working class win will inevitably have contradictory consequences, which are "functional" to capitalism. The same will be true of a "successful" reparation movement _under capitalism_, as it has been of the "success" of the civil rights movement.
The first step toward a practical opposition to the Right in a war of positions is to mobilize people who already are opposed to the Right but have been politically inactive for a host of reasons. Build your base, and move forward from there, while in the process re-defining terms of political struggles (including symbolic elements of them). That's the only practical way to break the functional trap, in my view.
