Let me just go ahead and fail that purity test for you. It took me a long time to come to a conclusion about this subject and it wasn't fully cemented until this conflict broke out. Millions of Palestinians refuse to spill blood. The Israeli state has encouraged funding HAMAS as part of their long term plan to prevent two-state solution viability. You can't build liberation on the backs of dead bystanders any more than the Nazis or the US or the Jacobins did. "But it's justified when we do it, you just don't understand" is a bullshit rationale that's older than dirt and twice as worthless; Jesus, how many times must the CIA have said that very thing to themselves over the years?
