Let me substitute the word compelling for "persuasive". Here in Australia, at least, and apparently throughout the Anglosphere, Palestinian voices are dismissed outright. When Anglo folk speak on this subject they are at least only accused of antisemitism. Their careers may well be jeapordised by well-resourced lobbying campaigns, but they are not threatened with deportation or investigated by the state for alleged terrorist sympathies, which is what happens to Palestinians, Arabs and Muslims who speak too loudly on this subject. But only Jewish voices can escape the basic formula whereby criticism of Israel is held to be inherently anti-Semitic and should therefore be excluded from respectable discourse, which means that these voices play a crucial role in airing truths that many would prefer to see buried.
