You have to understand the reason behind this whole 'Islam oppresses women' campaign.
Historically, in other cases of discrimination and oppression against gays, blacks and minorities, women tended to be more supportive of tolerance and understanding. Hence the anti-Muslim campaigners had to make sure women wouldn't feel empathy for the demonized Muslims. Therefore, they created this whole image of Muslim women as being oppressed. Never mind the fact that Muslim women themselves deny the charge and defend Islam -- the hatemongers dismiss these women as 'brainwashed'.
For the haters, Muslim women can't possibly be taken seriously. Like previous instances of 'savages' who didn't know what was good for them, it's the new "white man's burden" to 'liberate' Muslim women.
