I wouldn't call myself a feminist, but here's what I think...
On one hand, it's a dumb law. This is the twenty first century and in this country, men and women are equal. It's divorce and either spouse could be at fault--the man should not have to give up his money because the two are splitting. He earned it, it's his.
On the other hand, I think people can agree men and women are not truly of equal status. Please note that following is not true for all women and men and there are plenty of exception. Men are competitive, ambitious, and biologically superior compared to women. They like a challenge, they like expressing dominance and can get back up on their feet quickly. They're aggressive. Women, on the other hand, tend to shy away from conflict. They're passive and want communication and understanding. Giving a woman who he must have loved half his money makes it very clear who the dominant supporter is. It's just another way to show that men are superior to women in character, finance, and status. So, I say this law is dumb no matter how you look at it.
Though, looking at it, in marriage, nothing is just the man's or just the woman's. Marriage is an agreement in which two people agree to share their lives and even possessions. They both know beforehand that divorce would be costly, especially on the supporter. Divorce courts, also, cannot strip either one of everything and leave the other in the streets while the other is home free.
This is a tough topic, but overall, I do think it's a dumb law that enforces inequality and irrational social expectations no matter how you look at it.
