In terms of general discourse I'd say that's certainly true. The official Yes campaign has actually done a really good job avoiding those pitfalls, though. Everyone involved has showed an insane level of restraint (perhaps too much at times) given the absolute barrage of lies and blatantly bad faith misdirection they have been exposed to for months.

And I will add that I don't see this as left versus right in the way that other social policy debates are. Constitutional recognition for Indigenous Australians has historically had conservative support and in this referendum you can find many examples of right leaning people who support the Yes campaign. Chris Kenny on Sky News has been using his program to campaign for a Yes vote for months, as an example. Part of the reason it has taken so long to get a referendum on this is because great efforts were taken to establish a model that would receive bipartisan support.

In the modern era, I think politics is often less about left versus right and more about education versus misinformation. And that has certainly been the story of this referendum.
