You have to compare it to the alternatives.
Sure. Let's compare it to the alternative the morality is partially biologically hardwired and partially culturally determined. By comparison the idea that "history decides what's morally right" is silly.
Marx basically had the idea that you don't need God for an absolute moral system when you can pin it all on history
Yep, he had this idea. That doesn't make it a right idea. Marx had lots of ideas which didn't turn out well.
You observe how history moves. Then you extrapolate. You look at the limit of that function and that limit is the perfect morality.
Oh, so -- keeping in mind we're on LW -- the universe tiled with paperclips might turn out to be the perfect morality? X-D
And remind me, how well does extrapolation of history work?
In the US where Marx didn't have much influence as in Europe there are still a bunch of people who believe in young earth creationism.
Do you, by any chance, believe there is a causal connection between these two observations that you jammed into a single sentence?
Since culture evolves with history there is a lot of overlap between culture determining moralty and history determining morality.
