There have been plenty of splits and schisms over the centuries by those who thought their church had good off track.  The logic of staying within is simply that you think it may be possible to get it back on track.  Your differences may be limited to the specific women or gay issue which you may believe is resolvable or else you believe it is a fight worth fighting regardless of where it must be fought.  Even true believers rarely believe their Church is right at all times and all ways - and many engage in order to change that state of affairs. The problem for the CofE is that many of their most active membership are fundis and evangelicals and if they leave there isn't an awful lot left except an aging set of traditionalists and a very few progressives.
