Foreword: Sorry for the wall of text. I started typing and the words just kept coming. Feel free to ignore this. It's mostly a splattering of my thoughts about my experience moving from mostly neutral (and confused), to far-left and enthused to be so.
I've been a lurker, but I have to say, my experience with all of this has fortunately been very different.
I came here and to other leftist Internet places to challenge my ideas, and to expand my current knowledge. I've been consuming so much content lately, and it feels liberating.
The climax of this, though, has been my viewing of Philosophy Tube's series on Marx. I had decided at some point, "You know what? Screw it! I want to learn about what Communism really is! I want to really understand it!" And so I downloaded The Communist Manifesto from Marxists.org. I got about halfway through Part 1 before I realized I wasn't really understanding it. Marx is very difficult to digest, and I was feeling a bit ill and fatigued when I tried to read it.
My memory hearkened back to Philosophy Tube; I knew he had a series on Marx, but I'd yet to watch it. So, thinking that it might help me better digest TCM, I watched it. And, oh, my god. It became so clear. Aspects of the world I'd never fathomed, finally unlocked to my mind. I felt as if I had been emancipated from my ignorance.
And so, I've been reading and consuming more. I've been on a non-stop quest to learn more about Socialism, Communism, and, yes, even Capitalism. I had no understanding of what these were before.
There's a whole world of political philosophy I never knew about it, and if anything makes me angry, it's simply that I didn't know about this before.
But now I do. And I'm learning more constantly. I have a long list of Marxist, Anarchist, and Socialist/Communist reading to do, and it keeps getting longer. I suppose it's a good thing that I love this kinda stuff.
So my experience has been mostly positive. I don't come to feel angry. I come here to feel enlightened. My formally enormous world just got a whole lot bigger.
And my life has been enriched for the better by it.
