Schafly: Losing the War?

I first became aware of Phyllis Schafly from her anti-LBJ diatribe.  Needless to say, I was not impressed.  She is widely credited with stopping the Equal Rights Amendment in the 70's, and pulling the Republican Party to the right.  Corey Robin has an interesting take here.

I won't speak ill of the dead, but I'll muse on the significance of the ERA defeat.  It seems to me that American society has essentially evolved to where it would have been had ERA been passed. Yes, it's been a piecemeal progress, but progress it has been.  If I'm correct, it makes you wonder about the circumstances under which a constitutional amendment is vital, and when it's not.
