So maybe step 0 is: find people who know about them, before you can do the talking and reading. The New Yorker is my general go-to for measured introductions to new domains: the authors biases are fairly simple to spot when relevant (leftish-intellectual-in-US-terms) and the level of detail is usually high.
Sadly, I don't have a ton more at hand, other than one rule that I'd highly recommend to use as a filter: if you get the feeling the person is trying to make you angry, find something else. Polemics are rarely the best way to be introduced to a topic.
