Also, the idea that "there's politics in the source, but you can enjoy it without engaging with them" is sort of proving my Rage Against the Machine example from my original post (I picked the most overtly political band I could think of for the ad absurdum of it): Just because you don't CARE or agree with the politics, doesn't mean it's not there. I'm not saying you need to like, or engage with the politics in anything, but denying that they exist is...a political act!
As for your refutations of the people I picked, I didn't see you citing an example of a story Asimov had without politics/social commentary (the man was prolific and I haven't ready everything he wrote, I picked him because his best known works are Foundation and Robots series which are both very very political), if you felt The Man in the High Castle and Do Androids... (or Flow my Tears, or A Scanner Darkly) were just "being weird" and not political, again, I think we're just using different definitions of the word.
In H2G2, Adams says that Vogons, the galactic bureaucrats and face of the space government, make the 3rd worst poetry in the Universe. Now if one wanted to, one can make that a silly joke, or one could interpret that as people who are dedicated to maintaining the systems of government are the among least creative creatures in existence . And the weird thing is, somehow, even if one came to the 2nd conclusion, one could still think Adams wasn't making a political statement. Now why am I suddenly thinking about Claude...
