DSA did the same thing, we basically spent more time debating our exact position on Palestine than anything that could make us a relevant national org (like internal democracy), and nobody cares, like I couldn't even tell you how I voted or what outcome was.
Obviously it's a bit different as the Greens are an actual party, but anything more specific than self-determination is LARPing, did they at least pair it with something useful like a commitment to an arms embrago & BDS?
