Senator Leyonhjelm said his comments came in reaction to what he claims is Senator Hanson-Young's "misandry", meaning an ingrained prejudice against men.

"This is about misandry. The prime minister should stop being such a pussy. This is about criticism of all men. It's just as bad as criticism of all women."

Finally a politician willing to take a stand against all of this nonsense.

Senator Leyonhjelm claimed that Senator Hanson-Young "thinks all men are responsible for violence against women."

"That's offensive to men", he said, and that prompted his remarks.

He said he "won't be apologising or withdrawing" his remarks unless certain conditions are met.

"I've nominated conditions under which I would apologise, they include an acknowledgement by Sarah Hanson-Young that not all men are responsible for crimes that are perpetrated by some violent people, that we are individually responsible for what we do, and that women should be entitled to carry measures for their own protection and self-defence," he said.
