That's a really interesting way of looking at it! I think that the reason they get equated is that the material effect had been historically the same. Patsocs advocate for socialist policies, but ideologically restrict who does and doesn't get the benefit. Class reductionists advocate for socialist policies for all, but when the time comes to redistribute wealth, geez you know we really tried. So like the american socialist movements of the early 20th century, moved popular support for socialism all the way to a New deal. But Black workers were excluded from union membership or any of the benefits of the new deal, until the UAW started admitting black workers in Detroit decades later. So even though the messaging was completely different, the historical effect was the same. If workers have the power to demand truly transformative reforms, like new deal policies, then we have to actually push beyond that because the ruling class is never going to let it go down the way we know it has to. They will always fight back with extreme violence. Anything we win has to be defended and we can only defend it if everyone is on board to defend it, and not everyone will be on board if it leaves most people out. Maybe it wins temporary concessions for some, but we are communists, dammit! It's all or we fighting. Its not enough for the workers to be united. We have to be united in struggle, or we will never get there. At least that's what I think.
