While not really an explanation of the resistance to female bishops, it's a good acount of the Anglican/Episcopal schism.
http://www.guardian.co.uk/world/2010/jul/08/anglican-schism-historyThe first issue was women priests. Although a couple of Chinese women had been ordained as an emergency measure in Hong Kong during the war, they renounced their orders after the 1948 Lambeth conference, the 10-yearly gathering of Anglican bishops from around the world, which as far as possible decides what the communion stands for.
The American women who put themselves forward for ordination after the first wave of feminism in the 70s were less disposed to submit to authority. The 1978 Lambeth conference asked in vain for there to be no further women ordained; by 1988 the conference was trying to stop the Americans electing a woman bishop. In 1989 the diocese of Massachusetts chose Barbara Harris anyway.
But members of the Episcopal church of the US did not all share the liberal values of New England. In the south there was a noisy and well-funded conservative backlash. In 1998, the central arguments at the Lambeth conference were about gay people, and the conservative Americans, who saw this as the issue on which to avenge their defeat over women, recruited hundreds of African bishops to their cause in advance. One of these tried to exorcise a gay Christian in front of the TV cameras.
With the enthusiastic encouragement of the then Archbishop of Canterbury, George Carey, the conservatives pushed through the conference a resolution on sexuality which liberals could not accept. (more at link)
