I read The Handmaid;s Tale  years ago and even though it is set is a post apocalypse  Christian world,  it seemed to me a world based on Islamic fundamentalism, as if Atwood was using the very real abuse  of women by Islam as a basis to  slag Christianity.  Forcing the women of Gilead  to wear the handmaids gown is no different than forcing women to wear Hijabs and burkas.  The message was: if we are not vigilant, we will wind up like therm. 

Sadly, we are not vigilant and are winding like them.
