Bof - I realize that in your haste to bash any and all things American you failed to note people point things out like "arcane law." I'll agree this is a damned arcane law. Even here in South Carolina, a potentially illegitimate child isn't enough to nullify a divorce for physical or mental cruelty. My guess is that if she fights this on appeal she'll win easily. Certainly the exposure this is getting (this story was also in the Seattle Post-Intelligencer) could help grease the wheels of justice.
As for your slight on "if the news came from Iran.." how about Ireland? Divorce only recently became legal there and abortion still remains illegal. Are you going to foam at the mouth about the domestic abuses that occurred in Ireland too?
South Carolina - too small to be its own country, too big to be a mental asylum.
