I suspect that the New York chapter of the National Organization for Women falls into the ineffective category. It's hard to have a favorable impression of them when their president releases this statement:
Women have just experienced the ultimate betrayal. Senator Kennedy’s endorsement of Hillary Clinton’s opponent in the Democratic presidential primary campaign has really hit women hard. Women have forgiven Kennedy, stuck up for him, stood by him, hushed the fact that he was late in his support of Title IX, the ERA, the Family Leave and Medical Act to name a few. Women have buried their anger that his support for the compromises in No Child Left Behind and the Medicare bogus drug benefit brought us the passage of these flawed bills. We have thanked him for his ardent support of many civil rights bills, BUT women are always waiting in the wings.It goes on from there. Thanks to Feministing.com for flagging this
And now the greatest betrayal! We are repaid with his abandonment! He’s picked the new guy over us. He’s joined the list of progressive white men who can’t or won’t handle the prospect of a woman president who is Hillary Clinton (they will of course say they support a woman president, just not “this” one).
One wonders why many women are hesitant to embrace the term "feminist" even when they seem to hold such viewpoints. Who wants to be in company with people like the author of the above missive?
