Katha Pollitt has an "Open Letter from American Feminists", documenting the strong and consistent interest American feminists have had regarding issues of women's rights world wide (including the Islamic world) and demanding that media sources stop the ridiculous falsehood that American feminists stay silent on the subject.
She's collecting signatures at email@example.com . Just give her your name and how you wished to be identified (e.g., "David Schraub, Student, Carleton College"), and she'll add you to the list.
Feminism ought to and does care about women's rights the world over. The louder we proclaim that basic truth, the better.
