Except that feminism actively derides both the gender norms that say mothers are better caregivers and the US court system's bias against fathers in child custody rulings. There is literally decades of literature and other sources on these points.
A old, common talking point and accusation is that feminism is equivalent to female supremacy, and antifeminist groups recruit men who feel emasculated by women[1]:
> A second set of texts presents varieties of the contemporary masculinist response. Like its earlier incarnation, contemporary masculinist response is split between efforts to dislodge women's supremacy in the private sphere and support for men who are "wounded" in the struggle to exude an aura of masculinity in the public sphere.
> Men's challenges to women's perceived parental monopoly come from men's rights groups such as the Coalition for Free Men, Men's Rights International, and Men Achieving Liberation and Equality (MALE), as well as numerous fathers' support groups. These groups often deny that men have power in society, arguing that male supremacy is an illusion, along the lines of the illusion of the chauffeur: "he's dressed in the uniform and he looks like he's in the driver's seat," noted Warren Farrell, "but from his perspective someone else is giving the orders" (cited in Woldenberg 1986, p. 10). Masculinist texts claim that women and men are "equally oppressed" (Baumli 1986) and rail against perceived institutionalized female privileges, such as exemptions from the draft and advantages in alimony, child custody, and child support (Goldberg 1976; Haddad 1979). One critical review of these texts summarized their claims as follows:
> > Men, they say, are emotionally and sexually manipulated by women, forced into provider roles where they work themselves to death for their gold-digger wives, kept from equal participation and power in family life, and finally dumped by wives only to have courts and lawyers give all the property, money, and child custody to the women. (Messner 1986, p. 32)
