There's quite a few subreddits that fly under the administration radar but are full of mods and users with good takes on Palestine. A good one is /r/lostgeneration. Nominally it's a millennial-bitch-fest kind of place with lots of that bullshit anti-boomer generational-war crap that's a distraction from the real war (the class war). But when the topic turns to Palestine, they're firmly on the correct side of history.
