I'll bite - how the hell can it be revanchist in even the worst sorts of strawman? Revanchism is an ideology about reclaiming all territorial losses. The always negative outcome claim is questionable - even considering that it in order for it to be successful by definition they need overwhelming might to reclaim to hold it and it will impair peace for lesser processes. If massively and hopelessly overpowered like say a hypothetical small subset of radicals in the Cherokee Nation proposing to annex large sections of the United States it can pretty safely be declared 'long lost cause'.
That isn't really applicable to anything "Social Justice" - even metaphorically. The closest thing for revauncism would be found in white supremacists and chauvinists who believe they should have complete domain over society by being sole holders of rights or 'rights' over other people.
And even then that is a metaphor confused and stretched so thin that it is akin to thinking all alcohol should be kept far away from national borders for fear that if spilled it could erase the lines because it could do so to ink on a map.
