Honestly, I've been slowly picking up on it, and there's unfortunatley a lot of reading that I still have to do. It seems like a lot of initial primary sources have been intentionally ignored to form narratives, but primary sources are definitely a good take to understanding all the different perspectives that one side or another may have had in history.

However, in recent memory I'd say good historical introductions involve

• Videos on both economic or historical concepts by Academic Agent
• Tik History going over details around World War 2. That link is his mammoth work about the links between National Socialism and Socialism, but there's plenty of others.
• "Immigration And Culture" - Thomas Sowell - Goes over how human societies form in relationship to immigration, and how societies respond to immigration. Lots of historical examples and Leftist narrative debunking.
• "Conquests And Cultures" - Thomas Sowell - Goes over how human societies respond to conquests and subjugation. Lots of historical examples and Leftist narrative debunking.
• "Basic Economics" - Thomas Sowell - Goes over economics, but also completely destroys a whole litany of narratives that were spun by the Left, and how the terrible results were inevitable due to... basic economics.
• "The Vision of the Anointed" - Thomas Sowell - Goes over the history of Leftist narrative spinning and intellectual fads, their disastrous consequences, and why they never seem to learn, or even face consequences.
• "Intellectuals and Race" - Thomas Sowell - Goes over the history of racialism both in the US and abroad, and how the intellectual class uses racism and racialism in order to effectively guarantee positions in intellectual hierarchies with it, bringing near ruin upon the larger society in doing so.
• "Gun Control" which is a book written in 1965 spanning the history of gun control efforts in the early 20th century (there is a lot of forgotten history in regards to that subject)
• "For The Common Defense: A Military History of the United States" which is an excellent book on the military history of the US up until the 90's and shows it's roots in conflict, and doesn't try to paint a rose-tinted-lens on any side
• "Goldwater: The Man Who Made a Revolution" which shows how Barry Goldwater rose to stardom politically, and even though it was written decades ago, the Left's response to both him, and Reagan, and Trump are startlingly similar.
• "Anarchy USA" - A film by the John Birch Society which goes over the history of both Leftist uprisings and the Leftist revolutionary involvement in the Civil Rights movement.
• This is the John Birch Society - Which goes over the history of JBS, but more importantly, shows the tactics and strategies of Leftists which were actively seeking to destroy them at every available turn. It gives you a flavor of just how familiar the Left's strategies really have been.
• "Conscience of a Conservative" is basically Barry Goldwater's treatise on Conservatism, so that you understand how American Conservatism is supposed to work in contrast to the narrative spun by the Left about what Conservatism means to them.

In addition to that, I'll always recommend 2 others if there's even a chance that you are interested:

• "Knowledge and Decisions" - Thomas Sowell's masterpiece, but it is not an easy read. I would consider it one of the most important books written in the English language. It actually strives to, and genuinely answers, a fundamental question about human nature, and how people take information, reference experience, make decisions, and retain that as knowledge.
• "The Might Of Nations" - by J. G. Stoessinger - It is probably one of the finest political science books I've ever read. It does a very deep dive on how people and societies create what are called Nations, how they work, when/why they emerge, and how this all interacted with the late 20th century and the collapse of the European Empires, and the Cold War
