Curse of American politics, I guess, when one considers the Democrats to be "left leaning", then your whole political perception is skewed.
(The Democrats are significantly to the right of our centre-right party. People who call them lefties or socialists or commies amuse, confuse, and bemuse me.)
See Lysenkoism: https://en.wikipedia.org/wiki/Lysenkoism
Marx's ideas were refined by Antonio Gramsci who offered social Hegemony as a means to achieve the utopia. To the extent that science is a sense-making part of society it must be taken over by pro-marxist/communist forces. It's the only way to assure the success of marxism.

Stalin had thousands of Lysenko's critics imprisoned, I dunno how Marx would feel about that, but I have a feeling it wouldn't be particularly positive.
What does Hegel have to do with anything here? Adam Smith was also "routed in Hegel"...
Adam Smith published The Wealth of Nations when Hegel was 5 years old, and died when Hegel was 19, and hadn't published anything yet.
Lysenkoism still isn't evidence that Marx was anti-science.
But it's still leftist in origin and in ideology. Saying the modern wokified U.S. Left isn't leftist is just a No True Scotsman argument. Leftism and rightism are not narrow, specific things, they're more like inchoate moral intuitions that are given more concrete form by ideology and realpolitik. Individual leftist or rightist ideologies are often contradictory with each other. But the underlying sentiment is usually still recognizable as one or the other.
As someone who is a communist, the Dems have nothing to do with Marx, and they are about as capitalist as they come.
