read socialism utopian and scientific by engels.     people treating socialism like a religion is precisesly why most 'marxists' are retards.    start with principles of communism. but better you completely discard and forget tbe word 'socialism' from you head. read value price and profit, wage labour and capital. then you can read a contribution to the critique of political economy, and then finally you should start with david ricardo's on the principles of political economy and taxation. then you can begin capital volume 1. all of this will take half a year at least for a noob.
