[9][10] Leith Erikson started the #21fathers movement, named for the discredited claim that 21 men commit suicide each week because of family law issues such as child support and domestic violence orders.

[11] The Australian Brotherhood of Fathers campaign is based on anecdotal evidence from men's rights advocates Barry Williams and Sue Price.

[14] Leith Erikson was quoted alleging that the "gender pay gap is a lie" and that "if women are not in top positions in business or government, it's based on their ability to be there."

[18][19] One Nation has proposed new domestic violence policy, including a change to the laws that categorically restrict a father's visitation rights after a court awards an emergency protection order.

[22][23] The Brotherhood have advocated a series of public awareness campaigns attempting to shed light on this issue in the modern legal system, including #donotconsent and #notyourright.

#notyourright emphasises the financial and emotional burden on parents when access to children is limited by abuse allegations and child support payments.

[26] Leith Erikson is a board member of End all Domestic Violence (Endalldv); a small charity based in Robina Queensland that offers services across Australia.
