Marx was a social scientist, not a prophet. Marxism is a science, not a dogma. Marx's work should be studied, I feature his works in my basic Marxist-Leninist study guide, but that does not mean that Marx's words are holy. Marxist concepts have been extended and explained in ways more applicable to contemporary times, retaining Marxism as the foundation and applying it to present, ever-changing conditions. It's this flexibility and evolution of Marxism that turns it into a science, rather than a dogma.

One does not need to read On the Origin of Species to be taught and study evolution. Still a good idea to, but if textbooks that study the same basis and carry it forward to the modern day are created, then this is also good.

Christian teachings weren't written by Christ, people wrote about Darwinism that aren't Darwin, a person can be the namesake and originator of a philosophy but other scholars will continue writing based on their viewpoint.

You argue like Charlie Kirk. You think you have a clever gotcha and you can probably convince children with this, but there's no meaning. People don't read Newton when they study Newtonian mechanics either. Unless they're particularly interested; of course they can get something out of it, but you'd never start there. It's not weird to name a field after the person whose ideas kicked it off.
