If you want a more scientific understanding of socialism using data, math, FACTS AND LOGIC, Paul Cockshott is a must.
His videos clearly and concisely explain Marxist ideas and provide empirical evidence for them. Best of all, he has many videos for the crucial question "What would a socialist society do/look like" that go way beyond the universal healthcare or trains that you libs care about. He also has excellent videos that show how to get to socialism starting with laws we can implement now.
