She has released some of the messages, in which anti-vaxxers call her a "whore" and a "Stinky stinky liar!" as well as one that said, "You should get all the poison Vaccines the child get in one Shot! Hope you get cancer soon!""I'm absolutely up for a full-and-frank debate, but I'm not up for a political culture that continues to degenerate into the realm of threatened violence, sexism and hysteria and at some point we've got to push back on this," Hennessy said, the ABC reported.The minister said she decided to record a Herald Sun video, highlighting messages she receives from anti-vaxxers, in order "to shine a light on the fact that the anti-vaccination movement is not a peace-loving group of hippies.""They are an organized movement, largely stemming from the United State of America that are hell bent on misleading parents that vaccinations are unsafe."That's a dangerous message and one I'm going to continue to fight. Vaccinations save lives," the minister concluded.According to the new laws, which took effect on January 1, 2016,.
