Please stop pretending wikipeda is a greater source on Marxism than Marx is.

Never did- besides wiki acknowledges that there not the same, but still based on much of the same concepts;

Because one does not necessarily have to be politically marxist to be economically Marxian, the two adjectives coexist in usage rather than being synonymous. They share a semantic field while also allowing connotative and denotative differences.

...

Marxian economics, particularly in academia, is distinguished from marxism as a political ideology as well as the normative aspects of Marxist thought, with the view that Marx's original approach to understanding economics and economic development is intellectually independent from Marx's own advocacy of revolutionary socialism.[2][3] Marxian economists do not lean entirely upon the works of Marx and other widely known Marxists, but draw from a range of Marxist and non-Marxist sources.[4]

Marxian econ might not be politically Marxist, but saying all socialists against marxian-econ just shallowminded.

Now fuck off.
