Yes, that's true, and that sucks. I won't deny that, and I feel terrible for any man that happens too, and I wish the courts were truly gender-equal in this respect. But the flipside of always granting women custody of children is immense social pressure for women to give up their careers to raise children, or to at least face huge energy expenditures in balancing both that men don't, and on balance, I think women are still getting the shorter end of the stick. It's within your control to avoid marrying a bitch or to maintain your marriage; it's harder to dodge societal expectations that because you're female, you'll be a poorer employee. Given the choice between two problems, I'll pick tackling the one where I have more control over the outcome. Wouldn't you?

Most feminists don't focus explicitly on making it easier for men to intrude into traditional female-dominated activities like childrearing, but hopefully, as it becomes more normal for women to enter the same spheres as men, the reverse will hold true too, and the courts will be more likely to see men as equal and not inferior caregivers. So even if feminism isn't explicitly about helping men, I think it's still on their side.
