I think a lot of women have assumed that as 'transsexuals' have been around for a long time, and havent really hit the news, it is possible to return to a time when we called men 'she' out of politeness and they didnt push boundaries.
Women are saying no as they realise that its impossible to go back to a happy compromise on both sides, and are even questioning if this compromise ever existed.
Its just funny how the more academic or high profile feminists have been late to that conclusion.
