The fuck?
I don't understand all of the connotations of the phrase, (I doubt queensland parliamentarians do either). I do understand palestinians ancestral land is bordered by the river and the sea.
That said, this sounds very much like making wrong think a crime. Nobody is allowed to acknowledge that Israel used to be Palestine because that would upset the Israelis.
In Australia in the last decade there has been a movement towards recognising first australians as the traditional owners of the land on which we live and work. It's often mentioned in podcasts, emails, public announcements et cetera. More and more signage has both European and Aboriginal place names.
The term "truth telling" has emerged to describe the practice of acknowledging historical facts rather than pretending they didn't happen.
If a group of indigenous Australians chanted "from the desert to the sea", would that be hate speech ?
