If they allow gays to marry
I ride the bus with a gorgeous Pakistani guy. One day he told me that he couldn't wait for the gays to get the right to marry in this country.
"The government will not be able to outlaw polygamy any more," he said.
"So, I said, you claim to be a mainstream American now, but you want more than one wife."
"Well what if my wife is not able to have children," he said. "I wouldn't want to just throw her away. I would keep her and marry another woman."
"Wow, I said. Aren't you special? What if your first wife wanted to divorce you and marry a guy who didn't want kids? That way she could be his one and only wife."
He looked skeptical. I got the impression he is hoping his first wife is barren. That way he is sure to get two wives.
