Heard of the power and control wheel? It's a graphic or chart intended to illustrate the ways in which women in abusive relationships are controlled and abused by their male partners.
It shows the relationship of physical abuse to other forms of abuse: each part showing a way to control or gain power.
If you're Julien Blanc, a sick and abusive misogynist who calls himself 'a pick up artist', you tweet pictures of yourself with the control wheel, accompanied by the description and hashtag "may as well be a checklist.... #HowToMakeHerStay".
Less than a fortnight ago he denied he used the graphic in 'seminars' on dating advice but posted it because he "stupidly thought, you know, mocking it would be funny".
The 25-year old American also posted a video of himself grabbing and choking women in Japan, after which an Australian campaign led to a number of venues cancelling his so-called "bootcamps".
This man, who is by his own admission, one of the most hated men in the world, is planning to tour here in June of next year.
Thankfully someone had the good sense to post a petition on change.org to ask Irish authorities not to grant him a visa.
It states: "Do not associate Ireland with a man who chokes women around the world as part of his pick up game. Please help us stand with the women of Australia, the women of America, the women of the UK and women everywhere, and do not let Ireland play host to events where men are being taught how to violate and harass women."
The petition continues: "To allow this man into Ireland legitimises sexual assault."
At the time of writing it had almost 15 thousand signatures.
This week another man was talking about violence against women. This time it was a real man. One of the many fine men who are part of the White Ribbon movement. It's the largest male led organisation in the world against violence against women.
Tom Meagher's wife Jill was raped and murdered in 2012 while walking home, less than 500 metres from a bar in Brunswick, Melbourne.
He said this week that "the attitude of some men is that women are property and if you think manipulating women is clever, you're wrong. And if you think shoving a woman's face into your crotch is power, you are wrong".
He encouraged people to sign the petition to force the authorities to deny Julien Blanc a visa.
I know who I'm listening to and who I'm supporting this week. If you're clear about how you feel about violence against women, the website is change.org.
