The foundational belief of the Yes campaign, embodied in the Uluru Statement from the Heart, is that the Voice is something that indigenous Australians want. If this is so, the argument from guilt gets going, such as, why should non-indigenous Australians vote to not let these special people have their special rights?
But, it seems the core proposition of the Yes site is just false. Polling done by the No side is indicating tht the majority of indigenous Australians support No, and will oppose the Voice. This, if it proves to be true in the only poll that counts, on election day, it will knock the Yes side quite badly. In the aftermath if they dare rattle on about white racism, if the majority of indigenous people oppose the Voice, that claim will be knocked flat. How will we know? By polling after the vote to deal with the statistic of some indigenous people changing their minds.
