Sorry about your difficulties, comrade,and I think it's fine to engage with theory on whatever level you are able. But I can't in good conscience say that there's a better way of understanding theory than actually engaging with the text. Those things sound cool and good, but with the exception of the State and Rev with footnotes (which likely actually exists), you're getting someone else's representation of what they think is the most important in text.

That said, why is theory even important? Because it creates the conditions for praxis. It shouldn't be an end unto itself. If you get enough to direct the right actions towards the right ends, you're golden as far as I'm concerned
