Katherine Russell

When Karen Hunt Ahmed and her Muslim husband divorced four years ago, many friends asked her, “Now you can stop this Islam stuff, right?”

Some friends, she thought.

“Like it was a hobby I took up when I got married and now I’m supposed to drop it,” said Hunt Ahmed, president of the Chicago Islamic Microfinance Project, which she founded with two colleagues in 2009.

Hunt Ahmed, 45, is part of a growing sorority of female American converts to Islam, especially those who are or were married to Muslim men, who must deal with the perception that they converted to Islam because of domineering boyfriends or husbands.

The stereotype was revived in the wake of the Boston Marathon bombings, when news emerged that the wife of bombing suspect Tamerlan Tsarnaev, Katherine Russell, converted to Islam after meeting Tsarnaev in 2009 or 2010 when she was about 21.
