Actually, that's also true of natural science . Most of what scientists do is develop belief in things they can't _see_ such as atoms, extinct species, gravity, global climate change, viruses, et al.
Furthermore, natural scientists rigorously, rigidly and _dogmatically_ adhere to the scientific theories that have been proven within their discipline such as Newton's LAWS, LAWS thermodynamic , Einstein's LAWS, Charles LAW and Boyles LAW in chemistry. Natural science is big collection of natural laws which scientists adhere to like religious catechism ! With mathematical rigor in many cases.
So, as a SCIENCE, Marxism has basic principles , theories and laws ( see. _Capital_ ) that are rigorously adhered to by MARXISTS. This does _ not_ make Marxists's politics a religion, but rather it is critical to it being a science.
