> I can't think of an equivalent anti-female law with such devastating long-term impact on the woman.

Child support law in the United States doesn't discriminate. The office that handles child support may, as may the judge (I've heard stories of women given more leeway with payments than men), but both genders are able to be the obligor.

> in today's culture, men are also often treated extremely unfairly...

No, they are not, comparatively. It's not even on the same scale. There may be a handful of instances of men being treated unfairly, but pointing to a commercial where a man is portrayed as bumbling and equating that with the institutionalized sexism women face is ridiculous.

In fact, most of the instances of men being treated unfairly (child support, custody) are actually byproducts of sexism against women. Society places the woman in the role of the caretaker automatically.
