EFA should only promote groups who represent everyone equally. You wouldn't accept the KKK, why accept others who encourage equivalent prejudices.
If a section of society is marginalized and persecuted in the society as a whole, a movement to equalize things is bound to crop up. By your argument, you would prefer the African-American civil rights movement never to have existed, is that correct?
As a sidenote, I would like to remark that many feminists would like to define feminism as the struggle to end sexism for everybody. Consider this quote by bell hooks:
"In Feminist Theory: From Margin to Center, I suggest that defining feminism broadly as “a movement to end sexism and sexist oppression” would enable us to have a common political goal…Sharing a common goal does not imply that women and men will not have radically divergent perspectives on how that goal might be reached."
