The ANZACS fought for a free nation. The rainbow movement want to make it illegal for Australians to be able to speak freely and to believe openly. This is not a freedom promoting trade-off, it is the opposite, it subjugates, it spreads fear (fear of speaking freely, thinking freely, discussing freely, debating freely, investigating freely), promotes tyranny and authoritarianism.
The rainbow movement is demanding their views be elevated and recognized as normal and be forced on and affirmed by society, and in return they insist that everyone who disagrees with their view, especially the religious (mostly Christians and Jews), must be punished and persecuted for doing so. Put simply the same-sex "marriage" rainbow movement insist that our freedom of speech, religion and conscience be removed and replaced by an intolerant tyranny.
One change of one law (marriage) will hand them the full power of the law and State to crack down on all opponents of their worldview.
They insist that children must now be taught (the "Safe" Schools deception) that dangerous sex acts are now normal, fashionable, safe and encouraged. They cause children to suffer mental and physical abuse to advance their cause. They are leading impressionable youth to be seriously confused and to behave in ways contrary to mental and physical health.
Every child comes from and needs BOTH a mother and a father. Same-sex "marriage" intentionally keeps either a mother or a father from the child. Government should protect the child through upholding traditional marriage.
